What Happens in Pearl of the South Pacific: Full Plot Summary

The whole story of Pearl of the South Pacific (1955) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

Dan Merrill [Dennis Morgan] awakens on his boat after a night of drinking to find his former love, Rita Delaine [Virginia Mayo], there with his partner, Bully Hague [David Farrar]. Appealing to his greed, Rita and Bully coax him into coming along to an island where supposedly they can dive for a hidden treasure of rare black pearls.

On the island, the high priest Michael [Basil Ruysdael], a white man, has a son, George [Lance Fuller], who is about to marry Momu [Lisa Montell], the daughter of Halemano [Murvyn Vye], the native chief. The arrival of the boat carrying Dan, Rita, and Bully interrupts the wedding ceremony. Before the interlopers can be repelled, Rita poses as a missionary and George, who has never seen the outside world, persuades his father to welcome her to their isle.

After Rita's missionary clothes are stolen and burned by Momu, Rita ingratiates herself with the natives and infatuates George. He shows her a lagoon where the pearls can be found but refuses to dive, calling it taboo. Rita laughs and dives in, only to encounter a giant, deadly octopus.

Dan and Bully become more aggressive in seeking the pearls. Dan goes to the lagoon with George and together they slay the octopus. George does another dive for the pearls after making a deal with Bully for him to leave the island and never return, but Bully stabs him in the back and takes the pearls once George surfaces. The natives come after the newcomers and kill Bully with a spear. Halemano also orders Rita put to death but Dan rescues her during the process. Dan returns the pearls and decides, along with Rita, to remain on the island after their ship is destroyed by fire and explosion by the inhabitants.
