Surreal giallo about a delusional student who thinks he's discovered the identity of a serial killer.
Early one morning, Marco, an architecture student and lighting tech for a local theatre, puts up posters around the EUR district of Rome (Lazio) promoting the group's latest show. Whilst lost in his task, he hears a gunshot and in the search for its source, discovers a murdered young couple lying out on the pavement. The culprit of the murders hops on his bike and casually cycles away unaware of Marco's presence. Marco is struck by the casual indifference of the psycho-killer and feels compelled to follow him back to his home.
Haunted by what he has witnessed and unable to shake his unease, Marco feels compelled to return to the killer's house the next day and follows him to a local supermarket. Whilst stealthily tracking the man down the aisles, Marco witnesses the man stab a woman before casually leaving the scene of the crime rendering Marco in a state of shock. Marco becomes obsessed with the mysterious man and decides against reporting the crimes instead, continuing to voyeuristically watch the man kill; simultaneously horrified and intrigued by the senseless murders he bears witness to. This new found obsession begins to eat away at Marco's relationships; putting a strain on his romance with girlfriend Paola, further damaging his already frayed relationship with his mother and alienating his university friends. Yet Marco is seemingly unbothered, consumed by an overwhelming compulsion to partake in a silent game of cat and mouse that will inevitably end in his untimely demise.
