After the sale of all his zebus, with the help of Retovo, the boss of zébus "Ravelomana" slept with Clarissa, a prostitute of high rank. The day after, the taxi which was bringing him to his house was attacked by the Dahalo (highwayman) and he was killed by the chief of bandits. The gendarmes were investigating on the murder. Similarly, the son of the dead person, Boba was looking for his father's murderer. He was collaborating with Retovo, a door-to-door salesman who had advised him to attack a farm house with the stolen zebus and catch the chief of the bandits. Gendarmes, informed, got involved in the attack.
