Before her daughter marries a man she does not love, Chatterton reveals a dark family secret to her. In flashback, it turns out that Chatterton's lover, Nolan, was killed in the war after being sent there by her domineering father, Atwill. When it was discovered that Chatterton was pregnant
by Nolan, Atwill allowed her to keep the baby girl as long as she told everyone the child was her sister. When Chatterton finally admits the truth to her daughter, Atwill claims Chatterton is crazy and has her committed. This uneven script is poorly handled by over-direction.
