Cult director Massimo Dallamano made this surprisingly tedious thriller about a murder-for-hire plot. Lisa (Luciana Paluzzi) is the trampy wife of a jealous detective named Franz (John Mills), who has underworld connections from his job on the narcotics squad. Lisa's shady background and promiscuous habits drive Franz to a homicidal rage, so he hires a hitman (Robert Hoffmann) to murder her. As so often is the case in films about hired killers, the hitman falls in love with Lisa and helps her to double-cross Franz. Predictable and dull, this standard genre effort is below Dallamano's usual standards, and it features a dreadful musical score by Giovanni Fusco which only adds to the disappointment.
