Kitty learns that Matt's injured shoulder blade will be fine, but that he has a more serious congenital lung weakness. In spite of this, Matt is determined to race in the upcoming regatta-urged on by his father, a breezy, successful business man. Kitty quickly sees the danger of his father's influence on Matt-and Matt's father, for his part, does not want his son treated like an invalid and suspects Kitty will make him "soft." As Matt and Kitty begin to fall in love, the tension between Kitty and Matt's father becomes more acute, reaching a crisis when Matt's father warns Kitty to keep away from Matt, hints that he is much better than his son anyway, and tries to rape Kitty. Immediately thereafter, Kitty is puzzled to discover that Matt is checking out of the hospital, treating her very coldly.

Joanne meanwhile is fighting a losing battle in the hospital to assert her belief that nurses should be allowed to take more responsibility and thereby ease the burden for the doctors.

Michelle's detective efforts quickly put her in jeopardy, and a trail of killings and clues leads her finally to uncover the mystery-her boyfriend is in league with a seemingly benevolent old local doctor, who is the Quagran supplier. Lester kills the doctor and steals his money, trapping Michelle on his boat. Michelle refuses to go along with Lester's scheme and cleverly outwits him.

Realizing the woman will need an emergency transfusion, Joanne takes a blood sample and hurries to the hospital blood bank as soon as the ambulance pulls into Emergency. Later, Joanne is attacked by the woman's distraught husband-as a result of the emergency uncross-matched blood ordered by Joanne the woman has contracted septicemia, and the hospital is wide open to a lawsuit. Joanne is relieved of her duties until a special hearing is called.

Kitty is alarmed to find out that Matt is going to race in the regatta. She hurries down to the marina, where the boats are getting ready for the start . . . .
