After a night on the town, charmingly awkward Deb wakes up in the apartment of the most attractive guy in Portland, Maine. She's thrilled, but she can't remember much of what got her there. The handsome Ryan only knows it was a mistake and ushers her out the door... into a full-scale zombie apocalypse. Now, a walk of shame becomes a fight for survival as the mismatched pair discovers that the only thing scarier than trusting someone with your life... is trusting them with your heart.
