We are introduced to Jason Hawes and Grant Wilson, co-founders and lead investigators for The Atlantic Paranormal Society (TAPS). Their Technical Manager, Brian Harnois, tells them of an interesting case. The home they are to investigate is in Altoona, PA which is several hours away, but because of the dramatic nature of the case they decide to make the long drive. They investigate reports of poltergeist activity in a home with a very young girl who seems to see the spirits. After uncovering some dramatic Electronic Voice Phenomena (EVP) they return to the site and inform Brenda, the girl's mother, of their findings. Due to the long distance traveled, they decide to investigate two other sites while they are in the area. That investigation is continued in the next episode.

The team investigates the historic Mishler Theatre and the Altoona Railroaders Memorial Museum. At the theater, the owner and employees have seen the late owner walking into the wall where his old office used to be, sitting in the seats, and have heard him walking on the catwalk above the stage. At the museum, the spirit of a railroad worker has been seen. Despite some orb activity in the theater, neither site presents any good evidence of paranormal activity. During the investigation, Jason complains to Grant about missing equipment that Brian was in charge of.

The team investigates The Lighthouse Inn in New London, Conn., which is reported to be haunted by the ghost of a bride who fell down a flight of stairs on her wedding day in 1930. Drops in temperature are recorded, and Steve feels someone touch him on his back when no one else is nearby. They then travel to Ashland, Mass. to a pub called Stone's Public House, formerly The Railroad House. Here, a little girl died after being hit by a train. Glasses have been known to fly off the shelves, lights turn themselves on, and a number of other occurrences have been documented. The team records one EVP of a voice saying ""I'm not..."" and a strange light. The light may have been caused by an IR light source.

At the request of the US Coast Guard, TAPS goes to Long Island Sound to investigate the Race Rock Lighthouse. The lighthouse is now automated, but the Coast Guard officers who come to do maintenance and inspection have reported strange occurrences and are nervous about going to the site. The commanding officers hope to disprove the rumors. The team's cameras pick up strange orb activity and a fog which the investigators do not remember from the time of the video. Andy is able to follow an EMF (Electro Magnetic Field) reading that seems to move up and back down the stairs (following the course of the old caretaker when he would check on the light). More dramatic, one camera sees a chair move a few inches in an empty room. Jason tells the Coast Guard that the site does appear to be haunted.

TAPS investigates Eastern State Penitentiary, an abandoned prison with a long, colorful history and a reputation for paranormal activity. While there, they capture a strange, shadowy shape on film. After reviewing the film, Jason decides that the team should return. More orbs are caught on film, but no repeat of the shadowy figure. Efforts to duplicate the footage prove unsuccessful, but Jason and Grant see how it could have been done. Not wanting to ruin TAPS' reputation, they decide that the footage is inconclusive and put it up on the TAPS site so that the public can decide what they think.

This investigation focuses on some friends of Brian's whose home is a deconsecrated 19th century church. They claim to have seen apparitions and to have heard strange noises. Also, one of the doors in the house opens by itself. The investigation turns up only orbs caused by dust. Jason determines that the sounds and orbs are caused by the settling of the wood beams when the church bell rings. The team is able to duplicate the opening door, giving a mundane explanation. No evidence of a haunting is found.

TAPS is called to investigate an armory in New Bedford, Mass. In one room, the thermal imaging camera detects a warm mist passing in front of the lens. This is very strange, because mists are generally colder than the surrounding air. While moving along a catwalk, sound man Frank DeAngelis suddenly falls down and does not feel well enough to move for quite some time. When the video is examined, Jason sees that Frank's audio equipment actually jumps up with no visible reason and hits him in the face. The video is on the TAPS site.

Reports of disturbances in a college student group house are easily explained as acoustics and encounters with neighbors who were drunk at the time. At the Topton House Pub, witnesses have reported that the ghost of a little girl sometimes trips people on the steps and has moved glasses of soda on one table. The daughter of the owner has also smelled roses while in the cellar and heard murmurring voices. The smells and voices are explained, and no evidence is found of any other paranormal activity. Jason shows Frank DeAngelis the footage from the Armory.

Mike Sinclair, the founder of O.R.I.O.N. Paranormal and a TAPS family member, has called in TAPS to co-investigate the New Boston Inn, in the Berkshires. After examining his findings, the TAPS team is able to disprove or cast doubt upon, everything he found. However, the experience their own incident when a pen seems to have moved with no one else nearby. Next they travel to Pittsburgh to investigate the home of Gloria and Genny. Both of them relate dramatic experiences, but the team finds no evidence of a haunting.

TAPS investigates two cases. First they go to Albany, NY to the home of Linda Johnson. Linda claims to be psychically sensitive, and to have been accosted by a negative or ""demonic"" entity. No conclusive evidence is found, but Jason suggests that Keith Johnson contact her separately to try to help further. Next, they meet Adam Zubrowski, who seems to be experiencing strange events. The house was built by his grandparents, and his grandfather died there. Two odd EVPs are recorded, and it is judged likely that the house is haunted. One of the recordings sounds like Adam's grandfather.

Hooray for Hollywood? Actually, this time Hollywood is cheering for TAPS as they come in to solve some age-old mysteries in famed haunted locations. The season 9 opener starts at The Sowden House. This is the site of the Black Dalia murder. They meet Steve Hodell, whose surgeon father was the original suspect in the vicious attack. This is L.A.'s most infamous murder, where Elizabeth Short was surgically cut in half, and both halves were carefully posed on the side of the road. George believes his father murdered 9 other women in the basement. His sister, Rita, saw apparitions in the basement. Rita's experiences include seeing shadows in the night, hearing voices and other strange sounds- including chains being dragged. Everyone wants to know who these spirits are and what they want. An intensely personal request, which is what TAPS does best. Big news!! Michelle Tate, runner up from Ghost Hunters academy, is now joining the team. Everyone is excited to see her, and Jason reminds her that professionalism is key, and she needs to remember that not every noise is paranormal. During the investigation, K.J. and Britt monitor the cameras and notice a figure walking halfway across the room and then returning to the bathroom that was likely the murder scene. What is that?? It looks like half a human being, and Elizabeth Short was cut in half! Jason believes that whether the ghost haunting the house is the spirit of George Hodell or one of his victims, they would be more apt to reach out to Michelle. So she's alone in the bathroom, and hears footsteps and pacing. In the basement, K.J. and Britt mix the shadow detector and the laser grid technologies. They see odd movements and hear strange noises. Later, Michelle and Adam hear a woman's voice in the hallway. Analysis revealed that the footsteps Michelle heard in the bathroom were from someone outside, and the figure that Britt and K.J. saw turned out to be a crew member. Bummer! That would have been awesome evidence! However, the team managed to catch a recording of a child's voice saying "It's George and Charles", and another voice saying "Did you even know my name?" Rita feels validated about her feelings about her childhood home. TAPS help another client! Next: Madame Tussauds' Wax Museum. With the famous wax figures come frightening stories! What a freaky place to investigate! The client, John, says employees hear music after hours and the presence of someone with them. Employees claim Bette Davis' eyes move, and see figures (not even wax ones), and a sign turns on and off. Victor Killian, an actor, was beaten to death nearby. Is his ghost haunting the museum? Or are the wax figures just freaking people out? Britt and K.J. pick up crazy EMF readings, while Jason and Steve hear humming on the second floor. Wait a minute, Steve realizes it could be a backdraft in the elevator. Tango and Adam hear strange sounds, but when they investigate some mysterious shadow movements they realize blinking lights are the culprit- not ghosts! Debunked! Evidence analysis showed strange noises the team recorded, and convincing video of a figure crossing the Bette Davis Room. Jason tells John, the client, that this looks to be paranormal. But there's no way to confirm whether or not it is Victor Killian.

Kentucky sure has its share of ghosts! Tonight TAPS returns to the Bluegrass State to investigate The Belle of Louisville, the oldest operating steamboat in America. The beautiful and colorful exterior of this vessel isn't enough to cover up the ship's history of rumors, mystery and murder! Captain Winters, the longtime head of the steamboat, was not a nice guy. Apparently he sent one of his mates, Floyd, to the paddle wheel and then turned it on, killing Floyd! Winters later died on the ship of a heart attack. Mark Doty, the current captain, is skeptical of paranormal claims. But his crew has seen more than their share of activity. Shadow figures, moving blue lights, voices, whispering, doors swinging and even a face-to-face encounter with the ghost of Captain Winters! The crew is freaked out by the increasing intensity of the experiences, and suspect that the activity has moved to the neighboring lifesaving station as well. Captain Doty would like TAPS to put his night watchmen at ease. During the investigation, Britt and Michelle conclude that high EMF levels may be serving as a conduit for the spirits moving between the two ships. Jason and Steve chase footsteps from the boiler room to the ballroom to the gangway, but can't find the source. A mysterious swinging door catches Tango and Michelle's attention, but it turns out the wind is the culprit. Jason and Steve continue to chase Floyd on the neighboring ship, but determine that the high EMF levels on that ship could be causing the crew to misguidedly perceive paranormal activity. On the main deck, Britt and Adam see a large black shadow just where the ship crew claims to see figures, and they can't debunk it. Britt and Adam experience shuffling footsteps and flashing lights in the life saving station and continue to hear unusual noises. In the captain's quarters, they have shocking conversation with Captain Winters. Michelle and Britt then have a conversation with Floyd in the lifesaving station using a REM-pod. While a lot of claims were debunked in this investigation, during the analysis the team discovers recording of voices that weren't detected. Great investigating once again!
