Young and awkward, The Coast-Guard's ensign Thomas Garland suffers from the comparison with his late father, a war hero. Which does not prevent him from falling for pretty Kate Fairchild, a young woman who runs a sailing school. Of course the way he expresses his deep sympathy for the lady leaves to be desired. And the situation does not improve when a trio of bumbling jewel thieves interferes.
Mickey is performing routine maintenance on his tugboat (with interference from a pelican) when a call comes on the radio that there's a sinking ship needing assistance. Sadly, Mickey's crew consists of Donald and Goofy, so getting underway to help is not easy. Goofy has to fight a boiler's door to get it stoked with coal (and when he succeeds, he overfills it) and Donald gets tangled up in the machinery. Not to mention that nobody casts off, so they drag half the dock along with them. The overworked boiler soon explodes.
