This Japanese comedy is bookended by Frank Nagai's title song, and Nagai keeps cropping up throughout the film - even appearing in a rock face. At the suggestion of his friend, a lackadaisical vet, a repressed, henpecked, daydreaming pharmacist takes advantage of the fact that his domineering wife has gone off on holiday with the children to live life to the full. He begins flirting with the pretty girl working in the boutique opposite his shop. He and his friend go out for a wild night on the town before a madcap night time boat trip with the young woman reveals a few truths to our hero.
