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.
