Atouk (Ringo Starr) is the leader of a small band of misfit cavemen who are part of a larger community headed by strongman Tonda (John Matuszak). Atouk is madly in love with Tonda’s woman, Lana (Barbara Bach). He even ignores the advances of the lovely Tala (Shelley Long) and sets his mind to finding some way of wooing Lana. During Atouk’s quest for romance, he and his cohorts fend off dinosaurs, indulge in hallucinogens and invent cooking, music and medicine.
Workaholic Howard Langston (Arnold Schwarzenegger) wants to make things up to his son, Jamie (Jake Lloyd), and wife, Liz (Rita Wilson). He promises to get Jamie the hottest toy of the season, Turbo-Man — even though it’s Christmas Eve and the toy is practically sold out. As Langston hunts down the elusive gift, he runs into mailman Myron (Sinbad), another father on the same quest. With the clock winding down, Langston’s moral code is tested as he starts to learn the real meaning of Christmas.
