To save a film star's fingers, Toby Peters gives dance lessons .

Fred Astaire has a headache named Luna. The moll of a well-known Los Angeles gangster, Luna has demanded dance lessons from Hollywood's finest hoofer, and whatever Luna wants, Luna gets. But after two lessons with the lead-footed lady, Astaire tires of her making passes at him, and hires famously discreet private investigator Toby Peters to break the news gently. Trouble is, Luna and her boyfriend -- nicknamed 'Fingers' because he likes to cut them off -- don't take bad news well. To protect the star's digits, Toby attempts to pass himself off as a dance instructor. For his troubles, he earns a spanking from Fingers and a promise of more pain if Astaire doesn't come around. Not long after, Luna surfaces with a cut throat, never to dance again. Toby may not be a dancer, but to escape this deadly mire he has no choice but to stay nimble and keep his feet moving.
