Emile is a contract killer. A hired killer who travels by bicycle and who kills in exchange for a few tickets left in a small mailbox lost in the middle of the fields. This time, the man to be slaughtered is named Gaston Pouget and lives at 7 rue des Peupliers: a shed on the edge of a highway. Only here, when arriving on the scene: - SURPRIIISE!!! Emile is surprised by a birthday in honor of Gaston which should, a priori, arrive soon. Emile was not invited.
