After the murder of his beloved wife, a man in search of redemption is set adrift in a world where nothing is as it seems. On his journey, he befriends slacker Jimmy "The Finn", becomes involved in rescuing his neighbor Colette from her own demons, and gets entangled in a web of deceit full of unexpected twists and turns.

Alternately hilarious and horrifying, Overnight chronicles one man's misadventures of making a Hollywood movie. It starts out as a rags to riches story as Troy Duffy, a Boston-bred bartender, sells his first screenplay for The Boondock Saints.
