Danny Skeggs (Steve Coogan), a simple-minded and delusional pawn shop owner, meets Teresa (Julia Sawalha), a heavily pregnant homeless woman whom he takes in. Over time, the two begin developing a bond, but whereas Teresa only sees Danny as a friend, Danny falls in love with her. Danny becomes insanely envious when Teresa's child is born, so he sets out to get rid of the child in the hope that Teresa will love him.
