A trio of petty criminals – The Coward, The Fool and The Experienced, go "fishing". They do not only want to eat and drink well, but they also wish to catch a fish. But the conmen do not want to sit on the beach with a fishing rod and wait patiently for a fish to bite, instead they decide to go poaching; their plan is to stun fish using dynamite! Dropping a stick with a dynamite block tied to it into the river, the crooks rub their hands in anticipation of a magnificent "catch", but ... the unruly dog Barbos interferes. The dog manages to fish out the stick of dynamite which is about to explode from the river and rushes towards the poachers! In a panic, the scoundrels run away, but Barbos chases after them, and the three men climb a tall tree. But the cunning dog throws dynamite with a burning safety fuse under a tree, runs away ... and after that there is a loud blast! Poachers who were going to blow away the fish have instead knocked themselves senseless and their clothes get tattered to shreds.
