Plot
Opening quote: "There she paused for a while thinking... but the temptation was so great that she could not conquer it."
A young woman, Faith Collins, is running along a road, tormented by visions, and is hit by a motorist. The driver, Leroy Kent, calls an ambulance while a mysterious man arrives and suffocates her to death before disappearing. Nick (David Giuntoli) and Hank (Russell Hornsby) are called to investigate and find glass cuts in her arms. They interrogate her husband, Roy, as he has been reported for domestic abuse, but he doesn't reveal anything.
Following up on a social media post she made, Nick and Hank arrive at a bed and breakfast and question the owner, Billy Capra (Patrick Fischler). He says that Faith appeared at the B&B but didn't stay. He shows them the garden, where Nick sees Capra shift into creature form. Nick and Monroe (Silas Weir Mitchell) later identify him as a Ziegevolk, whose pheromones make women fall in love with him. Nick and Hank discover that other women have gone missing since Capra arrived in Portland, some of them later turning up pregnant. Capra is shown feeding three women caged up in his basement.
