Season 1

Investigative journalist Jeff Sefton has learned to laugh off his younger brother Nate's relentless string of obsessions, especially his latest rant that a hit TV show intends to harm him. However, when his brother mysteriously disappears, Jeff takes Nate's paranoia seriously, and in the process uncovers the dark underworld of the TV series "Cult" and its rabid fans, who are obsessed with the show's charismatic cult leader, Billy Grimm. As the show's gruesome plot twists begin to play out in the real world, Jeff enlists the help of a young research assistant Skye in a race to save Nate and unravel the mystery behind the TV series whose hardcore fans would literally kill to see what happens next...

Jeff enlists tech-savvy E.J. to help in his search for his brother Nate. Skye finally reveals to Jeff that she took the researcher job on “Cult” to learn more about Steven Rae. Meanwhile, at the production office, associate producer Peter Grey brushes off Skye’s concerns that some of the “Cult” fans believe there are hidden messages embedded in the show. On the television show, Kelly and Paz discover a body buried vertically, and Kelly believes that this might be a message from Billy.

Jeff finds a surprise visitor in Nate’s apartment who tells him about a dangerous on-campus game that Nate had been hosting known as "Being Billy," which involves role-playing scenes from past "Cult" episodes.

(Stacy Farber) searches Nate’s laptop and finds that he’s been active online and sent a cryptic email to a hidden recipient list. On the television show, Kelly confronts Billy.

Jeff tells Skye about Ama, a woman he met on a “Cult” fan site who claims that her husband is missing after becoming obsessed with the show. When they finally meet her, Jeff notices that she has a “Cult” notebook that looks eerily like Nate’s notebook. Ama introduces Jeff and Skye to a man who finds and deprograms cult members. EJ locates an IP address on a disk that could bring Jeff and Skye one step closer to finding Nate. Meanwhile, on the television show, Kelly finds Professor Patrick, the man who deprogrammed her, at Billy’s compound.

Jeff receives news that one of Nate’s friends might be planning something at an upcoming “Cult” fan costume party, so Jeff and Skye attend the party dressed as Billy and Kelly.

Also, at the party, Roger meets a mysterious stranger named Stuart. Meanwhile, on the television show, Kelly marries Billy in a flashback scene.

Skye collapses the morning after the “Cult” fan party, suffering a serious reaction to the drug she was slipped. The doctors urge Jeff to locate a sample of the drug so they can find a way to reverse its effects in order to save Skye’s life. Detective Sakelik arrives at the hospital but refuses to help. Jeff suspects that the drug might be hidden at her place so he takes matters into his own hands. Meanwhile, inside Skye’s hallucinogenic state, Billy, Kelly and Skye’s father Quentin encourage Skye to give up and stop searching for the truth.
