Ted (Zac Efron): handsome, smart, charismatic, affectionate.
Liz (Lily Collins): a single mother, cautious but smitten.

A picture of domestic bliss, the two seem to have it all figured out, that is until Ted is arrested and charged with a series of grisly murders. As concern turns to paranoia, Liz is forced to consider how well she knows the man she shares a life with and, as the evidence piles up, decide if Ted is truly a victim, or actually guilty as charged.
