Summary

Alone, disoriented and barely dressed, Marcus (Philip Winchester) wakes up in the middle of a cemetery. He has no idea how he got there. But this is not the first time this has happened. In fact, lately when he wakes up, Marcus has to ask himself the same startling questions: Where was I last night? Whom was I with? And how did I get here? Marcus suffers from a rare form of sleep disorder that causes him to do things in his sleep, which he can't remember the next day. Complicating matters, Marcus is disillusioned with his life and seeks solace in alcohol and women. Not only does Marcus not remember the name of the girl he was with last night, he can't even remember what they did together. Friends warn him, "Marcus, it's time to change your ways." Hoping to deal with his use of one-night-stands to escape his problems, Marcus joins a Sexaholics Anonymous support group, where SA sponsor Derek (Michael Badalucco) helps him work through his problems. While not initially identifying with the other group members, including porn-addict Rob (Patrick Labyorteaux), adulteress Olivia (Bellamy Young), and emotion-recluse David (Kevin Michael Curran), Marcus stays in an attempt to figure out his issues. One morning he wakes up next to Ann (Kelly Overton) who happens to be married to Marcus' best friend, Justin (Tim Draxl). When he tells Ann about his sleeping disorder, she is devastated. Their affair was never her intention, and she insists that last night he was the aggressive one. She struggles with telling her husband and decides to keep it a secret. This eats away at Marcus, but he doesn't know what to do. Justin and Ann throw Marcus a surprise birthday party. Marcus unwraps presents and receives a large knife that, judging from the handwriting on the tag, he appears to have sent to himself. The tag reads, "Use wisely. - Marcus." The next morning, Marcus wakes up covered in blood, the knife by his side, the police ringing his doorbell. He rushes to hide the evidence from the cops, all the while frantically searching for answers. His neighbor Becky (Lacey Chabert) might hold a clue when she mentions that she heard him leaving the apartment the night before. Then comes the news that Ann has been found dead, stabbed to death. Marcus is scared to put together the pieces, as he questions himself "Could I have murdered Ann ... In My Sleep?" Struggling to deal with Ann's death, Marcus processes his grief in his SA group, where he meets Gwen (Abigail Spencer), whom he covertly uses to help his investigation into whether he killed Ann. As conflicting evidence surfaces, Marcus wrestles with his past while he races to discover the truth -- hopefully before anyone else ends up dead.
