On the Micronesian island of Pohnpei, there are 1,000 year-old ruins that locals claim are haunted. This area, called Nan Madol, was actually brought to the attention of Destination Truth by an avid viewer who was visiting an area near Nan Madol when the tour guide suddenly refused to go any closer. A little research by the team revealed that there are centuries-old stories about floating lights and moving shadows at the site. If you're visiting northern Morocco, you just might hear someone talking about Aisha Kandisha, "the devil temptress." Although her name doesn't sound particularly threatening, this beautiful, nocturnal succubus is said to have been luring local men to their death for years. That is, of course, after she drives them mad with lust.

Josh heads into New Jersey's Wharton State Forest and teams up with Kris Williams from Ghost Hunters to search for the legendary Jersey Devil. In the next segment, he and his team go to China's Hubei provence in search of a Bigfoot-like creature called the Yeren.

Probes in Romania and Belize unfold.

The team travels to Fiji to explore a former cannibal tribe and the ghosts of its victims; the team visits the Philippines to locate a dangerous water monster.

Josh goes to Malaysia's Endau Rompin National Park to look into reports of Bigfoot sightings, then later, he goes to Argentina to find a lake monster called Nahuelito, reminiscent of Nessie that is supposedly lurking in Nahuel Huapi Lake.

In Bangkok, Thailand, the legend of the Naree Pon—a being that is half plant and half animal—has been gaining credibility because of a Thai temple that claims to have two of these creatures on display. These forest dwellers are said to have a small, feminine form, which enables them to blend seamlessly into the surrounding vegetation. The island of Cyprus in the Mediterranean Sea is the location of Josh's next adventure. He plans to investigate the thousand-year-old legend of a sea monster, which lurks beneath the clear, blue waters near the city of Ayia Napa.

Josh teams up with guest Allison Scagliotti of SyFy's Warehouse 13 and goes ghost hunting in two abandoned mining towns – Humberstone and LaNoria in northern Chile. Next, Josh goes to Rotorua, New Zealand to search for an eel-like monster called the Taniwha.

In Kolmanskop, a remote southern province of Namibia, Germans once erected a small diamond-mining town. The town has been uninhabited for more than half a century but recent reports say that the area is haunted. Could these be the ghosts of the many miners who lost their lives in the unforgiving heat of the dessert? In 2009, there was a report of a strange, hairless animal attacking a group of boys in a Panamanian town called Cerro Azul. The boys reportedly killed the animal by throwing rocks at it but when they returned, the animal was gone. Could there be a strange new form of life in Panama?

Josh and the team travel to Petra, an ancient city carved from the walls of a canyon in Jordan in search of the spirits who are still said to reside there. Then they return to the US to see if they can find proof of the existence of the Lizard Man who supposedly lives in the Scape Ore Swamp of South Carolina.

In Papua New Guinea, Josh hunts for a mermaid-like sea creature called Ri. In the next part, he searches for a dinosaur-like beast that lurks in the jungles near the village of Tinganavudu.

By day, the 800-year-old temple known as Angkor Wat is one of Cambodia's most treasured national landmarks and tourist attractions but, by night, could it be ground zero for the region's angriest spirits? That's certainly the belief of many visitors to Angkor, a sprawling forty square mile complex of stone palaces, shrines, and ruins. In the center of this compound sits Angkor Wat, a 12th century structure originally designed as a Hindu temple, which now holds the distinction of being the largest religious building in the world. Equally impressive is the massive, 600-foot wide moat that separates Angkor from the mainland. Might this moat be an ancient attempt to keep the bad spirits away from the local people? Sounds like a case for Team Truth. A 36-year-old fisherman just vanished in Canada's Okanagan Lake. Even worse, this is but one in a string of disappearances reported to have occurred in the same area of this body of water. The local rumor mill has it that all of these disappearances are the deadly handiwork of the Ogopogo, a huge amphibious beast, which has been documented in the annals of Canadian history for the past 1,000 years. The epicenter of Ogopogo sightings is the ominously named Rattlesnake Island, a small rock outcropping in the lake. Someone has to get to the bottom of this.

In the East African country of Kenya, the local Maasai tribe claims a massive volcanic crater is haunted by the 60,000 warriors who where killed there during a bloody civil war in the 1800s. Battle cries, shadows, and strange noises are all reported to emanate from the center of what's called the Menengai Crater. Could Madagascar be the home to a small but dangerous creature called the Kalanoro? That idea might not be too far fetched since this island off the coast of Africa is the home to several animals that are not found anywhere else in the world. Stories of the mischievous Kalanoro date back 2,000 years, but recent sightings imply the dangerous, two-foot tall, humanoid monster may be back.

Could Madagascar be the home to the beast known as the Fangalabolo, a bat-like creature with a monkey face? It's certainly possible since 90% of the species found on Madagascar are not found anywhere else in the world. Recent sightings of the Fangalabolo inspire Josh Gates to investigate. Zombie-like ghosts called Taotaomona are said to be roaming the island of Guam. Once revered by the Chamorus tribe of Gaum, these apparitions are thought to be the spirits of their ancestors. Recent reports, however, imply that the Taotaomona are becoming aggressive and attacking people.

Coiba Island, fifteen miles off the coast of Panama, was once the site of the infamously brutal Coiba penitentiary. Locals claim that the site of the prison is still haunted, which inspires Josh to investigate. In Argentina, a huge beast known as the Ucumar is said to lurk in the Andes and feed on livestock. This “Argentinean Bigfoot,” is described as having razor-sharp claws, thick fur and powerful legs. A recent uptick in sightings prompts Josh to look into it.

Robb Demarest and Dustin Pari help the team search in Peru for a gremlin-like creature. Also, the team plots a course to travel through the Bermuda Triangle.

The team heads to the Incan ruins in the mountains of Peru to research claims that they are haunted. Alaskan locals claim their community is being terrorized by a giant, winged bird.

Josh returns to Papua New Guinea, this time he is in search of a nocturnal, Pterodactyl-like creature called the Ropen. Next, he heads to Chile to find the legendary Chupacabra, a blood-sucking creature with glowing red eyes.

Josh and the crew head to the Ukraine and the site of the Chernobyl disaster where ghosts are said to be seen wandering around there. Also, a dog like creature is searched for in Cairo.

In the mid-season finale, Josh and the team travel to the kingdom of Bhutan, one of the world's most isolated nations. There, they hope to track down the Yeti monster, human in stature and beast-like in behavior. After a laborious trip from Los Angeles the team finally arrives in the land of peace and love. They speak to locals and quickly learn that the Bhutanese believe in the creature so fiercely they've created a Yeti Conservation Center in the southern city of Sakteng. One woman had bones passed on to her as an heirloom, which she believes are skeleton remains from a Yeti. So, Josh takes photographs that will be analyzed when the group returns to the States.

If you're a scuba diver, you've probably heard of the Truk Lagoon. Located halfway between the Philippines and Hawaii near the Chuuk Islands, this lagoon offers some of the best wreck diving in the world. Once the site of a decisive battle between Japan and United States during World War II, there are numerous ships, planes, tanks, and submarines that have been resting here since they were shot down nearly 70 years ago. Now, divers and locals claim that the ghosts of these soldiers haunt the waters around the wreckage. In northern Japan, you'll find many children's lunchboxes decorated with a cute, green reptile on the side. That animal, called a Kappa, was once feared as an evil cross between a demon and a turtle before it became something of a national mascot. Recently, however, a new spate of ominous sightings has given rise to rumors that the Kappa has returned and is responsible for missing livestock and even children.

In Bangkok, Thailand, reports of a giant ghost called the Phret are not unusual but recently, an amateur recording of this phantom climbing Victory Monument in the middle of town has locals in an uproar. If anyone can find these spirits of the dammed, which only manifest at high altitudes, it’s Josh Gates and Team Truth. A recent uptick in animal killings in Namibia has captured the attention of Josh and the crew. Not only have farmers been losing livestock, but the carcasses have also been completely drained of blood. Could the blood sucking be the vicious handiwork of the Namibian Night Stalker, a.k.a. the African Chupacabra? That’s what Josh wants to find out.

A Bigfoot-like creature is sought in Vietnam in the Season 5 premiere. (Special 8 pm start time.)

In Argentina, Josh searches for werewolves, which are of such a concern that the Argentinian president supposedly baptizes the seventh son born in a family to purge the curse. Afterward, Josh checks out reports near the same area, of a dwarf-like creature called El Pombero which is said to impregnate women with a single touch on the belly.

Josh and the crew investigate a manlike creature that is terrorising Cambodian villages. Elsewhere, Zambian fishermen claim that they are being stalked by a dinosaur.

Josh is on the island of Java in search of a bat with a 12-foot wingspan (that's not a vigilante). Then the team heads to the Philippines to hunt down a huge, mysterious river creature.
