Roman Polański directs Leon Niemczyk, Jolanta Umecka and Zygmunt Malanowicz in this psychological drama about a couple who take a hitchhiker on a boat trip with the intention of creating tension. 

Dead Calm in reverse, here the interloper with the knife is under threat from the couple as they toy with him. It makes for a sexy, brutal and gripping 24 hours on the lake which announced Polanski as a major talent. I was utterly hooked throughout.
