Plot

After recurring dreams, action star Tony is transported to prehistoric times where he encounters dangerous dinosaurs and love-seeking cavegirls. He must use his skills to survive, win his dream girl's heart, and potentially return home.

Haunted by recurring dreams of Hea-Thor (Denise Ames), a gorgeous cavegirl,and a menacing Allosaurus, action-movie star Tony Markham (Jeff Rector) soon finds himself transported, by means of a magic Icon, back through time to Dinosaur Valley. Now trapped in a world of dangerous dinosaurs, grunting cavemen and a tribe of exotic, love-starved cavegirls, Tony must put his modern-days skills to extreme tests in order to survive prehistoric perils, win the cavegirl of his dreams and (maybe) return to his own time?

Movie star Tony Markham (Jeff Rector), who lives with starlet Daphne Adrian (Griffin Drew), is haunted by dreams of a weird Icon, live dinosaurs and beautiful cave girls, and the obsession with one particular cave girl starts interfering with his normal life. Tony and a concerned TV reporter, Audrey Benedict (Elizabeth Landau), find their origins in a museum of prehistory. Tony recognizes an Allosaurus' skeleton as that of his dream dinosaur. The paleontologist, Dr. Benjamin Michaels (William Marshall) and his assistant Karen Forster (Carrie Vanston) show Tony stone slabs with cave art depicting the Allosaurus and cave girls. Among them, Tony finds the Icon of his recurrent dreams, which supposedly may grant three wishes. Tony wishes to be with his dream cave girl... and disappears.

Tony is zapped back to a stone age in Dinosaur Valley, where strange, primitive creatures from different prehistoric eras coexist. He encounters Mesozoic reptiles (including the Allosaurus), brutish cavemen led by hostile Beeg-Mak (Harrison Ray) and his dream cave girl Hea-Thor (Denise Ames). Someway, Tony loses the magical Icon. Hea-Thor and Tony are attracted to each other. Escaping the Allosaurus, Hea-Thor takes Tony back to her cave which is hidden from the cavemen. There Tony meets the other Dinosaur Valley Girls, all beautiful in various colors and hair styles: Tam-Mee (ARKENI), Bar-Bee (CAREE), Tor-Ree (S. G. ELLISON), Ded-Bee (STACI FLOOD), Bran-Dee (NINA KELIILIKI), Mee-Shell (DONNA SPANGLER), long haired blonde Buf-Fee (MICHELLE STANGER) and redhead Bam-Bee (LAURYN VEA), ruled by the elder woman, Ro-Kell (Karen Black), the estranged mate of former tribe chief Ur-So (Ed Fury). Tony learns that the cave girls, fed up with their menfolk's brutish ways, fled to this cave, and live apart from men. Tony, the only man around now, naturally becomes quite popular among the girls.

The more time spent in the past, the more Tony adapts to the primitive lifestyle, while teaching the cave girls about modern life. He resigns himself to being stranded in the past, as long as he is with Hea-Thor. Tony teaches some wrestling moves to the girls, who just love him being around them. A jealous cat-fight over who gets Tony's affection first, ensues between Buf-Fee (MICHELLE STANGER) and Bam-Bee (LAURYN VEA), with the girls Buf-Fee snarling and miowling like angered cats.

Meanwhile, the cavemen discovered the lost Icon, and through it, the secret location of the girls' cave. While Tony and Hea-Thor are elsewhere, they raid the cave and make off with their lovely captives. Tony Hea-Thor set off to rescue the cave girls, as they are attempting to free themselves thanks to the modern fight methods Tony taught them. After a big battle, the tribe, reunited, is menaced by the Allosaurus, which Tony defeats using explosive grenades he has created.

After a brief return to modern times, Tony returns back to B.C. times, to fight and defeat a disgruntled Beeg-Mak.

In present time, Daphne takes over Tony's role in the movie series. Back in time, the happy cave people begin to act "modern", and Tony, more than ever the caveman, stays with Hea-Thor in Dinosaur Valley.
