Elijah Wood turns in the performance of a lifetime as Frank, a shy unassuming young man with a terrifying hobby. When not managing his mannequin store, Frank enjoys stalking, then scalping young women. When he meets Anna, a beautiful young artist who asks for his help with her upcoming exhibition, Frank desperately tries to keep his homicidal instincts in check, but as his affections for Anna increase, so too does the urge to kill.
