A pair of elderly men, friends for 40 years, find their relationship stressed when they set up housekeeping together in order to save money. Exploring similar ground to that covered in Neil Simon's play The Odd Couple, which spawned a movie and a television series, Ce Cher Victor explores the tragic and dramatic aspects of the story. The two friends, meek, sensitive Anselme (Bernard Blier) and blustering Victor (Jacques Dufilho) are swiftly driven apart by circumstances.

The story opens in a Western saloon, where a young musician with a banjo begins to tell a tale of Lucky Luke and his sworn enemies the Dalton brothers: Joe, William, Jack and Averell. Luke has, once again, as he has done many times before, thrown the four outlaws into jail. The prison is also the abode of a guard dog named Rin Tin Can (Rantanplan in the original French language version).

This thin French drama takes place on a barren prison island. Pierre (Omar Sharif) has been sentenced to a life of hard labor on an island which lacks even a proper prison building: the men live in tents year 'round. Despite the grim conditions and brutal guards, he manages to hold his temper in check. His wife (Florinda Bolkan) campaigns for the right to visit him and finally succeeds. His inner discipline disturbed by her visit, Pierre reacts almost normally to abuse from a guard, and tragedy follows.
