Výhra admirála Kotrby (1981)

Former sailor Kotrba, nicknamed Admiral, has one dream, to take his own ship to sea. He has been building it for five years and now it is finished, but he still lacks the money to buy an engine. Then Kotrba gets lucky - he wins a voucher for goods worth 10,000. But there's a hitch. He can only redeem the voucher for goods at the local shop, where he has become the 100,000th visitor.
