Garvin is hiking in Snowdonia with his wife and daughter. Everything is great until they get separated from the group and a snowstorm forces them to take refuge in a cave. As Garvin leaves his family in hopes of rescue, he nearly freezes to death. He is rescued and brought to a strange place where he is now a beloved captive and quite content, except for the fact that he has no idea who he is. His backpack would surely give him clues, but it's the one thing his captors forbid him. Slowly, old memories of his former life and family start to resurface. When he confronts his captors, they are forced to share who and what they really are, but now that he knows, he may never leave . . .
