Plot

Trainee Captain Cunningham proves himself inept when his mistake strands Merrill's tour group in a hurricane. Jean Carter has mixed feelings about meeting her birth mother. Isaac takes a cruise as a passenger and meets passenger Mara.

Isaac (Ted Lange) is on vacation and decides to go on the cruise, as a passenger. He acts like a jerk and hooks up with another passenger (Lola Falana) and doesn't tell her what he does. Among the other passengers is a woman (Donna Mills), searching for her birth mother, who is also on the cruise, and she wants to go see her but is too afraid to. She meets another passenger (David Birney) and they hit it off. A rich girl (Barbi Benton), who just got dumped at the altar, is very mean and Doc (Bernie Kopell) sets out to help her. A couple (Edie Adams and Avery Schreiber) who are in a rut and are considering separating. An old woman (Audra Lindley), who is not all there. Stubing's (Gavin MacLeod) Deputy Captain (Dick Martin), is there to be groomed for when he's made Captain but he's a bit incompetent. When the deputy captain gets a message that there's a hurricane coming, he's suppose to give it to Stubing but runs into the old woman (Lindley), who is lost and he uses the message to draw her a map and she takes the map with her and he forgets about the message. Stubing decides to go to an island and the rich girl, the couple and old lady join him, along with Doc, Gopher (Fred Grandy) and Julie (Lauren Tewes). But when they get there, they find a hermit (John Astin), who holds them captive.—rcs0411@yahoo.com

"Marooned" begins with the arrival of a familiar passenger - Isaac Washington, whose planned ski vacation falls apart when there is no snow. So he changes his plans and boards the Princess as a passenger. The official passengers include henpecked Everett Buell and his sharp-tongued wife Maureen; spoiled rich girl Kiki Atwood, who was dumped shortly before her wedding; soap opera star Mike Adler; Isaac's foxy potential love interest Mara Carroll; "mature lady" Mrs. Worth; and Jeannie Carter, an orphan who grew to adulthood. Also on board is Deputy Captain Cunningham, a bumbler who is doing an internship under Captain Stubing en route to commanding his own ship. A radio operator receives a telex about an approaching hurricane, and gives it to Deputy Captain Cunningham. Before Cunningham can give it to Stubing, he is interrupted by Mrs. Worth, who is searching for her cabin. Cunningham uses the telex as scrap paper to draw a crude map of the ship, which he gives to Mrs. Worth; consequently Captain Stubing doesn't see it - at first. When the ship docks in port, Stubing entrusts temporary command to Cunningham, then takes Gopher, Doc, Julie, the Buell's, Kiki, and Mrs. Worth for a side trip. As Stubing leads the group through the jungle, their launch is stolen by David P. Crothers, a hermit who kidnaps them in hopes that they will give him a surprise birthday party, and locks them inside a hut. And then the hurricane hits...
