Sailor Frankie Martin is offered a thousand pounds by a millionaire in disguise if he can earn a hundred pounds in a week by honest means. Frankie tries his hand as a boxer, a bouncer and a commissionaire, and finally finds success as a singer. He also falls for the charms of night club chanteuse Julie, and this leads to further success when he wins a recording contract.
