Un flic (English: A Cop; also known as Dirty Money) is a 1972 crime thriller film, the last directed by Jean-Pierre Melville before his death the following year.

The gang escape with only part of the loot and drive back to Paris, where they place Marc in a private clinic under the alias "Schmidt".

As the press reports that one of the assailants was injured during the robbery, Simon, Louis and Paul set out to transfer Marc out of the clinic before the police search the facility.

Meanwhile, Simon descends from a helicopter onto the speeding train, breaks into Mathieu's cabin, neutralises him with chloroform, and is successfully winched up with the drugs.

Furious that the drugs were not recovered, Edouard berates Gaby and slaps her around for supposedly providing him with false information.

As Simon emerges from the hotel carrying an attaché case full of heroin, the waiting Edouard draws a gun and tells him not to move.
