As the Senegalese troops are about to be transferred out of the camp, they learn they will only be given half the pay for their service as the French troops are unfairly converting French francs to Senegalese francs at half the rate to save money. The Senegalese troops capture the camp and take a French general hostage, beginning a mutiny. The mutiny ends when the officer gives them his word that they will be given their proper pay.
