Both Rachel Holt and Diane Waring are up for a part in Kevin's latest production. In order to pick which actress will win the role, director Budd Blake (Scott Brady) suggests that they allow each actress to try out on horseback. Rachel knocks over a barrel while Diane rides flawlessly, so Diane gets the part.
Rachel has a chip on her shoulder, since she blames every loss in life on the fact that she was given up for adoption and raised in foster homes. She resents Diane, who comes from wealth and social prominence.
Diane attempts to befriend Rachel by allowing her to ride her personal horse, in preparation for any future part that might require equestrian skill. While out on a ride, Rachel comes across a young boy in her path; the horse rears and the child is knocked down. Rachel leaves the boy and returns Diane's horse, attempting to conceal the accident. The boy is hospitalized and the police suspect Diane as the guilty party.
Unwilling to betray Rachel, Diane does nothing to defend herself, and even Kevin, who is romantically attracted to her, believes she is guilty. Finally Rachel goes to the hospital to see the injured boy, and realizes that she has to confess. Diane enlists the help of her lawyer father to help Rachel avoid criminal consequences.
