The Boy Cried Murder.

A young lad with a penchant for spinning elaborate yarns gets himself in deep trouble when he tries to tell people that he really did witness a terrible murder. Unfortunately no one believes him--except the killer. This multi-national drama/thriller, set within a resort community on the Adriatic Sea is a remake of the 1949 film The Window. A screen adaptation of a Cornell Woolrich story of the same name.
