Gopher (
Fred Grandy) returns from vacation with a new girlfriend, named Gail Cowler (
Taylor Miller), who is a history teacher. He also has a trunk carrying a suit of armor, which he dons in order to impress her. But when Isaac (
Ted Lange) tries to help him get out of the suit, he breaks the bolt and traps Gopher inside. Captain Stubing's (
Gavin MacLeod) longtime friend Joan Heinsley (
Ruth Warrick) was widowed in a drunk driving accident, years earlier. The pain of losing her husband never completely healed and now intensifies as her daughter Vanessa (
Denise Miller) falls for Webb Jones Junior (
Laurence Lau), the son of the drunk driver who took Joan's husband's life. Reverend David Ruland (
Robert Pine) leads a mission study society on board the cruise, but two of his members, Betsy Dunvar (
Janine Turner) and Laura Tenley (
Sharon Gabet), are smitten with him.
