April Lopez (Charo) is back again, this time as a Spanish tutor to Bradford York (David Hedison), the proper headmaster of a New England boys' boarding school. Brad was widowed four years earlier and wouldn't approve of her chanteuse habits, which may go on display when the planner/entertainer cancels and Stubing (Gavin MacLeod) presses Julie (Lauren Tewes) to find a replacement. Lonely widow Grace Bostwick (Jane Powell) plans to throw herself overboard, but a white-suited man named Gabriel (Hugh O'Brian) claims to be her guardian angel and may be able to stop her. After ten years of marriage, newly-divorced George and Gwen Finley (Gene Rayburn and Jayne Meadows) are vacationing, together, on the same cruise. But their enjoyment is cut short when both of them suffer injuries and wind up in the infirmary, together.
