Kapitan z Oriona(1977)

After only a few years of training, the top student at the fishing school is appointed captain of a fishing vessel. The experienced crew of the Orion - a bunch of old sea dogs - openly show their dislike for the new captain, a youngster with no experience. The conflict deepens as a result of the captain's "bad luck"—the ship is not catching fish even in places where it used to catch a lot. It is only when the captain discovers the cause, which is a malfunction of one of the devices, that he is fully rehabilitated in the eyes of the crew.
