Never Say Die (1924)

A corps of noted physicians mistakes the buzzing of a bee for heart tremors and erroneously gives Jack Woodbury 3 months to live. Jack's avaricious friend, Hector, persuades his sweetheart, Violet, to marry Jack, intending to pick up an easy inheritance by marrying the Widow Woodbury. Jack fails to die at the appointed time, and Violet finds she has fallen in love with him.
