Thérèse was convicted of murders committed through terrorist acts; Henriette was convicted of negligent homicide in the death of her child; Raïssa murdered her husband. These three felons are on a train from one holding area to another. While the train is stalled in Lyons due to a railway strike, the three escape supervision and strike out on their own. For a while, they simply stay together and rejoice in their newfound freedom, but soon they quarrel and each seeks to make their escape more permanent. However, none of their efforts to contact helpful outsiders works, and soon it is the middle of the night. They meet back in a park and decide to try and pick up some men instead. When the strike ends the next morning, they are actually considering returning to prison.
