Having served her prison sentence honestly and disciplined, Cheyenne has decided to completely leave behind her criminal life. For the past three months, she has been living in Dunkirk, working on a ferry between France and Great Britain, and saving money for a trip to Brazil. Lola, a young and beautiful Parisian, arrives in the same town to get married. However, there is an obstacle - her beloved man is already married. In a fit of passion, Lola kills her rival, but it is precisely at that moment that Cheyenne happens to be nearby. The former convict realizes that it will be difficult for her to justify herself, and in order to avoid going back to prison, she is forced to cover up the murderer. Thus, the fates of two completely different women become closely intertwined, but why not use this to punish all the offenders?
