One fine day, at about 10 am, in a suburban house, three men, in their thirties are waiting for a fourth buddy. When he arrives, they plan to hold up the local bank where Séverine, their accomplice, is waiting for them. This could well be the beginning of a thrilling crime story, but these tough men, sporting tattoos, are not what they appear. "On fait comme on dit" is a comedy, and these guys could be descendants of the Keystone Cops. They are dreamers not gangsters. So much is riding on this bank heist, the pressure is intense.
