Italian remake of Hitchcock's 'Strangers On a Train' from director Maurizio Lucidi. Stefano (Thomas Milian)'s wife (Marisa Bartoli) is seriously cramping his future plans and he's looking for a solution. A chance meeting with the wealthy Count Matteo (Pierre Clementi) leads to an outlandish plan where both will do each other a murderous favour to free them from their respective problems. Stefano, however, treats this as a joke whilst Matteo is deadly serious. As events spiral out of his control, Stefano is driven to the edge of sanity in a deadly race against time.
