Marguerite Clark stars as Nesta, the daughter of canal-boat skipper Mike (Robert Conville). When she expresses a desire to attend a circus, Mike refuses, telling her the story of how her mother came to grief when she ran off with a circus performer. This serves only to make Nesta all the more desirous of visiting the Big Top, if only to locate her long-lost mother. True to her heritage, she falls in love with a performer, but when time comes to select a husband, Nesta chooses a down-to-earth doctor from her own community. The Robert Vaughn cast as Nesta's boyfriend was no relation to the much-later star of TV's Man From UNCLE; on the other hand, Still Waters co-star Philip Tonge was the same person who played character roles in such postwar films as Miracle on 34th Street.
