Later that night he finds an unconscious teenager in the Bois de Boulogne (a cruising park) who was apparently also hustling and has been beaten and robbed.

The two begin a relationship that is purely sexual at first but later develops into a romantic connection and savage serial killings by the pair of older or defenseless gay men.

The film now introduces a young boy also named Vassili, who lives with his mother Anna, a former prostitute who has a similarly hard time letting go of the past.

Young Vassili hears the moaning sounds, sees his mother limp and apparently unconscious between the two men in bed, and believes they have killed her too.

He runs out of the house and tells the police about the murders; early the next morning they apprehend Vassili and Angelo.
