Five young men aged about twenty form a tight group of friends. So there is a major panic when one of them, Nabil, dies during a quarrel that gets out of hand. The friends clear away the body and decide to keep silent to the outside world about what happened, but their friendship is tested to the utmost. Then they meet Pierrot and Madonna, two loners who have just met and, as a result of a joke played by the group, get married to each other.
