Summary: A topless, painted woman dances at a ritual sacrifice of a screaming tied woman. All drummers and attendants are women. Dino feet approach and we see briefly a slobbering bloody dino mouth.

Cut to military plane and the narration of Captain Jason Briggs, introducing Sergeant Ben Healey, pilot Corporal Buzz Branagan, and three privates under arrest for going AWOL: Wilber "Turbo" Turbowski, Wayne "The Brain" Kincaid, and John Skeemer (a smirky Steve Guttenberg wannabe). The plane goes down so we can have credits.

They raft to an uncharted island with Buzz hurt. Their gear from the crash is mysteriously gathered. Skeemer is glad to have his Playpen magazine. Turbo alone sees a female warrior, until all hear splashing and discover women with spears. Skeemer cries "Yabba Dabba Doo" regarding what he refers to as the "hooters on those babes." Meanwhile, a dinosaur has attacked Buzz and Wayne on the beach. The soldiers shoot at it, but the women with spears arrive and drive it off after it has eaten Buzz. "Surrender or die," claims a warrioress, wanting to kill "Uncle Sam." That the Captain claims to give orders raises a laugh among the women since men are "brainless beasts. They march off at spearpoint.

Coming upon a bronto, the woman has to reassure them that "Thunderbeast will not hurt you." The men are made to kneel before the Queen of the tribe, who says, "Take their fire-spears." The woman suggests, "Maybe they can save us from the Great One." Skeemer: "Jackie Gleason?" They are sentenced to work in the pit, but the Captain and Sergeant rebel and escape while the other three are recaptured. Skeemer's smiley-face tattoo saves them as the mark of the savior. Back to the queen. In famine time, predicted the sacred scrolls, five gods would emerge from the ocean and deliver the tribe from the Great One. The soldiers must slay a dinosaur.

Three warrior princesses, later dubbed Miss April, May , and June in reference to the porno mag, bathe topless in front of the soldiers. We learn that missionaries taught them English and disappeared into the jungle trying to kill the Great One. The men are given back their guns, and they give the women the magazine, claiming it is a sacred scroll. Wandering about, Skeemer exclaims, "Look, it's the worst creature of all, the Sarge-asaurus." The reunion of the five is interrupted by a triceratops attack. They shoot repeatedly and kill it, but Sarge is killed too.

At the burial ground, Wayne's wounded arm prevents him from helping to dig the grave. May takes him into the woods and a hot spring, performs a ceremony, and heals his arm with the water. As thanks, she asks Wayne, "Teach me page 34." Sex ensues.

The triceratops kill will feed the whole village for a week. But the Queen notes that this is "just a baby beast of armor. The Great One is ten times as big." So the men must die. June challenges the Queen to a ceremonial duel to save their lives. Chick fight. Party.

An insect problem accounts for the famine, and Wayne concocts a pesticide. Skeemer plans to date April and ropes cowardly Turbo into helping him hunt pterodactyl, her favorite food. Their prey escapes, though, so Skeemer passes off some turtle instead and teaches April "kiss," until she screams, "Dear gods, the Great One." Skeemer: "Hey, I haven't even taken it out yet." A tyrannosaur roars and chases them to a cave, where Skeemer discovers gold, starts collecting it, but is attacked by the beast of the cave. He spears this creature in the mouth.

The Captain is taken to the Queen and they agree to get the men off the island. She gives him a map to where a radio and supplies are buried from another wreck. April and Skeemer meanwhile discover a gigantic blue egg of the tyrannosaur. After wisecracking and mugging at the camera, Skeemer talks April into sex. The Captain digs up supplies and ammo. All are summoned to the Queen again. The women are next in line for sacrifice in a couple days at the spring equinox, although there's a question about virgin sacrifice qualifications.

The four soldiers and the three women undergo a mission to the egg to slay the beast. They await in a cave. Turbo and June walk together and, since Turbo is fat, balding, and pock-marked, we don't have to see them having sex. The T-Rex meanwhile is attacking the village and biting the arm of one warrior. The final scheme is to use June as bait for the T-Rex. She screams, attracts the dino, and the others attack. Turbo lobs a grenade into the mouth of the tyrannosaur and blows its head off.

Skeemer and April are married; the Queen convinces the Captain to stay on the island; everyone is full of smirky glee; and a baby tyrannosaur looks on and laughs.

Commentary: This is real "USA Up All Night" fare--sleaze-lite--the kind of film that almost makes me ashamed to have devoted my entire life to dinosaur films. It does have the examples of fixation on the dinosaur mouth though! (See? Told ya!)
