Becoming Human - Season 1 (2011)

Brandy Mulligan seems a likely suspect as Matt has recall of being in a girls' changing room so Christa and Adam pursue Brandy, pointing out that they know she is a member of the notorious Crompton family. Brandy is hostile but Matt suddenly recalls that he saw her leave the changing room so that she cannot have killed him.

Matt remembers school bully Danny holding his head in the toilet but again cannot recall if this was his last memory. Adam and Christa are concerned that they might be wrongly seen as a couple but are interrupted when they see Mr Roe argue with another teacher Mr Swan, whom Roe accuses of being a bully himself. Christa tumbles to the fact that CCTV in the boys' toilet might give them a positive answer about Danny.

CCTV footage leads Adam and Christa to the gym, where they hide in the vaulting horse as Swan comes in and vigorously attacks a punch-bag. He is aware of their presence but when he discovers them they pretend to be passionately kissing. Matt, who fancies Christa, gets the wrong idea and has to be told they are acting in his interests. A full moon is due soon and werewolf Christa feels this may be to their advantage.

The trio become certain that Matt was killed in the gym and Christa, transforming into a werewolf, is convinced that her heightened sense of smell will lead her to the body and thence to the murderer. For his own safety Adam has to lock her in a cupboard but next morning after she has changed back they make a discovery.

The trio discover Matt's body in the cupboards containing the gym equipment but they are interrupted by the actual killer, who explains their motive for murdering Matt. There is a fight, during which the killer passes through the door intended for Matt, who now considers staying around with his two new chums.
