Tony and Lisa, two policemen of the special team, have long been on the trail of Mancini and his men, involved in drug trafficking.
Finally, they defeat a large part of the gang by seizing the heroin during a shooting in a Chinese restaurant, but Mancini manages to escape.
Elvi, Tony's wife from whom she is separated, asks to settle in his apartment (promising to find him a new accommodation) and in the meantime takes some photos of an abandoned villa for her real estate agency.
When Elvi and Tony meet over the divorce lawsuit, the woman is shot and killed.
