During Atouk’s quest for romance, he and his cohorts fend off dinosaurs, indulge in hallucinogens and invent cooking, music and medicine.
Shallow, rich and socially successful Cher (Alicia Silverstone) is at the top of her Beverly Hills high school’s pecking scale.

When Tai becomes more popular than she is, Cher realizes that her disapproving ex-stepbrother (Paul Rudd) was right about how misguided she was — and falls for him.
