The team of Commissaire Ballestrat from the Territorial Brigade stakes out the hideout of a dangerous criminal named Sarlat.

Suddenly, Commissaire Fush and his team from the Anti-Gang Brigade arrive to the site.

The ambitious Ballestrat would rather let Sarlat escape than allow the rival team to take credit for the arrest.

She later betrays him by informing her boss of the Anti-Gang's upcoming operation to capture Sarlat's accomplice Manekian.

While the rest of the police prefer to wait the situation out, Fush single-handedly confronts Sarlat, and they are both killed in the resulting stand-off.
