Despite being a camp classic, this film often drags. The premise is simple: two tribes, Goona and Wongo, inhabit an island. The women of Wongo are beautiful, while the men are ugly (by which I mean average looking), while, predictably, the women of Goona are ugly (really ugly; one of them looks like Divine on a bad day) and the men are handsome. This paves the road for great conflict, but also paves the way for long boring stretches of canoe paddling and stupid subversive plotting.
The film opens with amusing credits done in a cave painting motif, and notes that one of the star Wongo women, Wana, is "Adrienne Bourbeau" (Barbeau) in a very early role. The other Wongo women get monikers like "Omoo" and "Ahtee." The central fixture of Wongo life is worshipping a "dragon god" which is actually a small alligator. (This was filmed at various tourist traps in Florida.) Women go talk to the alligator, and then interpret the alligator's instructions for the tribal leaders in between frolicking in their authentically native sundresses and bikinis.
This film has loads of filler, and manages to get boring at an alarming pace. Also frequently featured is a highly annoying parrot that mostly squawks, but also encourages the women to wrestle each other (with much hair pulling.)
Of course a man from Goona shows up and the Wongo women swoon while the men plan to kill him. The women foil their efforts in one of the least plausible screen moments in history. Trivia buffs please note that as the Goona man makes his escape (by canoe) the background music is the exact same music as used during the "resurrection of the dead" scene in Ed Wood's infamous "Plan Nine From Outer Space!" This is a welcome break from the rest of the soundtrack, which is highly bassoon intensive.
I would have given this film two stars, but there is one scene that earns it another: the "sacrifice dance" scene, which features the Wongo women writhing about led by a Queen in an alligator headdress. I have not laughed quite so hard in a while.
As the film winds down we see a woman wrestling a small alligator for what seems like an hour, followed by a call-and-response sacrifice ceremony reminiscent of the loyalty vows in "The Wild, Wild World of Batwoman." This leads ultimately to a unique fight scene featuring men with clubs against women with spears against an alligator. (The alligator wins.)
Of course everyone knows how this is going to work out: the ugly men and women pair up, and the attractive men and women pair up. This leads to much rejoicing, mostly from the audience, because their 72-minute nightmare is finally over.
This is fun viewing once for strictly camp value, but most people wont need to see it any more than that.
