This short was released in connection with the 20th anniversary of Warner Brothers' first exhibition of the Vitaphone sound-on-film process on 6 August 1926. The film highlights Thomas A. Edison and Alexander Graham Bell's efforts that contributed to sound movies and acknowledges the work of Lee De Forest. Brief excerpts from the August 1926 exhibition follow. Clips are then shown from a number of Warner Brothers features, four from the 1920s, the remainder from 1946/47.

Anna Case sings a song while the Cansino family dances in the background.

Helen Merrill sings and dances in the rough Western mining town of Nugget City, where she befriends Myrtle Cadby, whose husband Jake cruelly abuses her. After a particularly vicious beating, Myrtle, seriously injured, shoots Jake. As she lies dying, she gives Helen a letter of introduction to a man she was to have married in the East, urging her to leave Nugget City. Before she leaves, Helen overhears Bill Sheridan and "Snipe" Roach scheming to sell Charles Taylor, a wealthy New Yorker, a salted mine, with the assistance of George Reed, Taylor's mining agent. Helen goes East and learns that Taylor is the man whom Myrtle was to have married, but because she immediately falls in love with him, she conceals her own identity and masquerades as Myrtle.
