A marine musical comedy from Denmark. The radio operator, Hjalmar Olsen, lives in Nyboder. He handles all the problems for the Nyboder friends when they are in trouble - on land or at sea, from the sister's heartache with the less real rich man's son, the stoker's daughter's problems with an intrusive man, to a mutiny that breaks out on a foreign ship. Hjalmar is a man of action, who always acts quickly - and cheerfully - well supported by the gallery of brave boys and sailors.
