Sam Alvarez doesn’t just open locks. He’s the key. Living in Bellemer, Iowa, Sam leads a typical small-town life. When he’s not looking after his Nana or dealing with his mother’s expectations, he runs a one-man locksmith company. Unlike regular locksmiths, he can open anything with a touch and a wish, but Sam keeps that secret to himself. No reason to alarm the neighbors, after all. And if he sometimes feels an indefinable pull to do more with his life, well, that's probably just indigestion. Then one day, an unsettlingly beautiful out-of-towner asks for Sam’s help to open a door. Only one problem: The job’s in a graveyard. And the client? Turns out she’s Death. Maybe that’s two problems. When Sam unlocks more than he intended and demons come out to play, he discovers he’s far more than a locksmith with a hidden quirk. Now, he needs to figure out who he is and what he’s been called to do before darker forces close the door on him for good.
