Nothing But the Truth is a 1929 American pre-Code sound comedy film starring Richard Dix, loosely adapted from the play by James Montgomery and the 1914 novel of the same title by Frederic S. Isham.
Meanwhile, E. M. Burke (Berton Churchill), Frank Connelly (Louis John Bartels), and Clarence Van Dyke (Ned Sparks) bet Bennett they will pay him each $10,000 if he tells the truth for 24 hours.
The men later go to a nightclub where they meet Sabel and Mabel Jackson (Wynne Gibson and Helen Kane), who are a gold-digging sister act.
They are determined to hold Burke to his promise to finance their idea for a show and won't take no for an answer.
Mrs. Burke (Madeline Grey) learns from Robert that her husband had promised to back the sisters' show, which makes her furious.
