When the dinosaur families get trapped in a valley by an ice storm, one family of "spike tail" dinosaurs volunteers to leave since they consume more food than the others. Meanwhile, the young dinos and a new adult dinosaur named Mr. Thicknose, head out to bring back their friend Spike, who has left his friends to be with members of his own species.

Ray Tango and Gabriel Cash are narcotics detectives who, while both being extremely successful, can't stand each other. Crime Lord Yves Perret, furious at the loss of income that Tango and Cash have caused him, frames the two for murder. Caught with the murder weapon at the scene of the crime, the two have no alibi. Thrown into prison with most of the criminals they helped convict, it appears that they are going to have to trust each other if they are to clear their names and catch the evil Perret.
