Three poachers - Byvalyy, Trus and Balbes - are drinking on the river bank. With them is a mongrel named Barbos. Swinging wide, Byvalyy throws dynamite tied to a stick into the river. The Dog Barbos, accustomed to bringing diarrhea, instantly rushes into the water and returns, pulling a charge with a burning cord in its teeth. The poachers are terrified to flee from Barbos. After a long cross with many adventures, poachers climb the tree. The Barbos, putting the dynamite under a tree, prudently hides in a ditch. A deafening explosion is heard, black smoke envelops the tree.
