Sam's birthday is coming up and Devon decides to make it the best birthday that Sam has ever had. But the festive mood is put to a halt when a person from Sam's past makes an unwelcomed appearance.

Samantha arrives at Charles University and she reveals that she can not afford a meal plan. She meets her new love interest, Devon Sylver, and just as things start to look good for Samantha, it all comes crashing down when something tragic happens. Meanwhile, actress Dawn Vargas arrives at Charles University in search for a normal life but she gets drunk at the local University hotspot, a club named Colony, and Trent, the bartender, decides to help her.

Samantha attends the club fair with her new friend Dawn and quickly decides she wants to join a sorority. However, there is only one spot available and her competition becomes Kathryn. Kathryn, knowing that Samantha has a better chance of getting in the exclusive sorority than she does, decides to dig up some dirt on Samantha's life. While at Colony, Sam finds Kathryn making out with Beau, the boyfriend of the sorority's leader, Sloane. After Sloane confronts Sam about the dirt dug up by Kathryn, Sam decides to tells Sloane about Kathryn and Beau. However, Sloane is not impressed by Samantha's intentions. Meanwhile, Sam and Devon's relationship begins to blossom, but it does not last long.

Samantha becomes stressed over her upcoming exams and temporarily moves in with Dorothy to get some quiet study time. Sam visits Cynthia in the hospital and is determined to find out what is wrong with her. Meanwhile, Dawn's diva attitude causes the entire cast and crew of "Macbeth" to quit and Sam discovers Cynthia's secret.

Sam tries to deal with the aftermath of kissing Trent and she decides that she cannot trust him. She tries avoiding Trent but it proves difficult when Sam has to see him at work. Meanwhile Colony gets robbed and Sam and Trent are locked in the backroom. And Devon's jealousy issues get the best of him and leaves Sam a message on her phone that he later regrets.

Devon and Sam's relationship has become serious and Devon tells Sam that he loves her but Sam doesn't know how to respond. Sam tries to mend the relationship between Dawn and Trent, but the circumstance proves to be much more difficult than she first anticipated when Trent makes his feelings clear to Sam.

Trent asks his father to help Sam find her biological parents. Despite his disapproval, Trent agrees to have dinner with Sam and his parents at his parent's house. Meanwhile, Professor Fisher discovers who ruined his marriage.

Samantha and Devon get back together and when all the pieces seem all to fall in place, a new problem ensues. Devon and Sam decide to go to the Halloween party at Colony dressed as ketchup and mustard. Everything is fine before Cynthia shows up drunk and dressed as relish. Sam becomes torn between spending time with her new boyfriend or Cynthia. When Sam finally confronts Cynthia, she does something shocking.

Patrick returns and Sam learns that Dorothy isn't as honorable as everyone thinks. Dawn realizes Devon is still in love with Sam and Beau assaults Kathryn.

After Samantha complains to Darryl about the noise from her roommate, Kathryn, in her dorm room, Darryl imposes an eviction bylaw to anyone who makes excessive noise in the dormitory.
