Orphaned at an early age, Sandra had come to live with Mr. Northey and his two boys, Tom and Greg. Now the three are grown up, and Tom Northey is about to be married. This should be a happy day for all, but Sandra is miserable. Not only has she loved Tom all her life, but she was the one who introduced him to his beautiful bride-to-be, Nadine, and now Sandra is to be a bridesmaid at their wedding.

Further complications set in when Linda Baxter, a childlike blonde, enters their lives and apparently wins Greg's affection. Surprisingly, this leaves Sandra in a state of turmoil over her love for Tom and her sudden feeling of awakened interest in Greg.
