A little peasant girl claims to have been raped. The detective who arrives in the village discovers that it is a set-up, but at the same time reveals carefully hidden and very surprising truths about each.

The story is about a lieutenant, nicknamed "the Rooster of the Regiment", a married man, who just can't help running after any woman passing around, and one of his friend, who always has "good ideas" to give him a hand to come out of "ubuesque" situations.
