Sophisticated showgirl Doree Macy (Bebe Daniels) has long enjoyed the attention of wealthy older bachelor John Thornley (Lewis Stone). In town for a show, she accepts an invitation to spend the night aboard his luxury yacht. There, she makes the acquaintance of his younger, married business partner Bob Byrne (Ben Lyon). Although he is initially cold toward Doree, Bob is soon seduced by her during a morning swim. While John gallantly steps aside for Bob, Bob's wife, Connie, (Natalie Moorhead) returns and complicates matters. Ping-ponging between the two men, jaded Doree finds herself facing heartache and a breakdown. Sizzling with the very real sparks flying between soon-to-be-married costars Bebe Daniels and Ben Lyon, My Past startles with its raciness even today. Joan Blondell also stars in this archetypal pre-Code drama from the cowriter of Night Nurse. Roy Del Ruth (Blonde Crazy) directs.
