A young boy learns to take control over his life when he is shrunk to the size of an insect and has to sail his own toy boat through a flooded café. Morten has to be shrunk down before he can grow up. Morten builds a toy boat which he crews with insects. This is his escape from the unhappy world of the harbour café where he lives with his aunt Anna. When he is shrunk in a botched magic trick he finds himself sailing his own boat across the flooded café. The insect crew look uncannily like his aunt and the people she orders around. Morten has to reassess his relationships, save the crew from shipwreck and take control of his life.
