Lu fears that a little girl who keeps getting injured might be being physically abused by her dad. Andy suspects her nanny is stealing valuables from the house. Peter gets through to an insensitive husband of a pregnant woman about the pains of carrying a baby.

Lu faces an ethical dilemma about her doctor/patient confidentiality when an abused, pregnant woman appears to be missing. Andy confronts a doctor whose chauvinism may have cost a patient her life.

When a patient of Andy's takes a turn for the worse under Lu's watchful eye, the two doctors butt heads over whether proper procedure was followed. Meanwhile, Andy questions whether or not she can trust her oldest daughter. Also, when Andy and Morton try an experimental xenotransplant (using the heart of a chimpanzee), Peter questions the rights of the animal.
