Molly Morris, a private investigator based in Dallas, takes photos of cheating men. During one of her investigations, F.B.I. Agent Armon Ranford, offers her a job with the F.B.I., to watch over Alex Patrone, the daughter of a Senator, who was involved in an organized crime case. Molly is reluctant at first, but ultimately decides to accept Ranford's offer. She goes undercover as a sorority student named Brooke Stonebridge and receives help from her father. She meets Sasha Stolezinsky, the head of the sorority and other members, including Becky, Cotton, Hunter, and Alex, whom she has been hired to protect. At first, she thinks that Sasha may be a suspect, but as it turns out, she only changed her identity from Suzy Walters so she could start a new life rather than continue to be an outcast. Molly also meets her love interest, Nicholas Dexter, another student at the college. Molly begins to suspect one of her professors, Professor Talloway, when she discovers that Alex secretly goes off to his home on a lake. She continuously reports back to Ranford, who at one point tells Molly that Nicholas Dexter, her love interest, is not his real name. She does not believe him, and soon figures out that Ranford is not who he says he is. One night, she follows Alex to Talloway's home, only to discover that her professor is actually a federal agent. She encounters a gunman, who she escapes from. She figures out that Ranford is actually behind the mask, who drives off with a kidnapped Alex and soon finds Talloway injured from a gunshot wound outside his home. When she returns to the sorority house, she encounters two federal agents working on the case. They are hesitant to believe her at first, but Morris convinces them to help solve the case with the help of her sorority sisters. They execute the plan, rescue Alex, and corner Ranford, who is arrested. Alex hands over a SD card, with the evidence in her father's case, to Molly who hands it over to the F.B.I. The F.B.I. is pleased with Molly's work, and she is offered to continue working for them. She declines, and instead wants to continue going to college. Two months pass, and she is taking photos of a guy Cotton is dating. Nicholas comes up to her, revealing they are dating and they kiss as the film ends.
