Wren is a high-school senior who can't wait to get away from her dysfunctional family. On Halloween, Wren's mother decides to go out with her much-younger boyfriend, leaving Wren to look after little brother Albert.

Enlisting the aid of her sassy friend, April, and two other classmates, Wren sets out on a frantic search for her sibling.
