Dancing feet (1936)

Peyton Wells (Ben Lyon) rescues Judy Jones (Joan Marsh) from a very dull young man, at a sedate party given for her by her multi-millionaire grandfather Silas P. Jones (Purnell Pratt.) Judy refuses to accompany Peyton on a slumming trip to a cheap dance hall, and Peyton dances with several of the dowagers and tells them that Silas is practically dying of scarlet fever. The guests hastily depart and Joan joins Peyton at the Dreamland Dance Hall. She is mistaken by Jimmy Cassidy (Edward J. Nugent) as one of the hostesses and decides to dance with him as a lark. One thing follows another and Judy gets disinherited and takes a job at the dance hall through Jimmy and his friend Mabel(Isabel Jewell.) Jimmy confides to Judy his ambition to become a dance instructor over the radio and Judy decides to help him but can't get the needed financial backing. She gets Peyton to front the money, promising him she will reconsider his offer of marriage if Jimmy's plan fails.
