1969. Ted (Zac Efron) is crazy-handsome, smart, charismatic, affectionate. And cautious single mother Liz Kloepfer (Lily Collins) ultimately cannot resist his charms.

For her, Ted is a match made in heaven, and she soon falls head over heels in love with the dashing young man. A picture of domestic bliss, the happy couple seems to have it all figured out … until, out of nowhere, their perfect life is shattered. Ted is arrested and charged with a series of increasingly grisly murders.

Concern soon turns to paranoia - and, as evidence piles up, Liz is forced to consider that the man with whom she shares her life could actually be a psychopath.

This is the story of Ted Bundy, one of the most notorious serial killers of all time.
