The O'Donnells are a typical, everyday family -- Tad (George Hernandez) is a sensible working man, his wife (Fannie Midgely) is a good mother and their daughter Kathleen (Constance Binney) is pretty and innocent to the point of naiveté. Kathleen works in a factory and its owner, Donald Holiday (Warner Baxter), has taken a shine to her. But instead she falls for slick cab driver Harry Stanton (George Webb), who insists, "Honest, kid, you're the only girl I ever loved." Kathleen falls for this, and when her perceptive father makes clear he doesn't approve of Stanton, she moves out on her own.
