Valdis Nulle is a young and ambitious captain of fishing ship 'Dzintars'. He has his views on fishing methods but the sea makes its own rules. Kolkhoz authorities are forced to include dubious characters in his crew, for example, former captain Bauze and silent alcoholic Juhans. The young captain lacks experience in working with so many fishermen on board. Unexpectedly, pretty engineer Sabīne is ordered to test a new construction fishing net on Nulle's ship and 'production conflict' between her and the captain arises...
