A huge meteorite has plunged into the Great Valley, cutting off the water supply and causing tension among the once-peaceful dinosaurs. While the adults argue and turn against one another, Littlefoot and his friends venture out to find a new source of water, only to be constantly bullied by a trio of older dinosaurs. The journey becomes a fight for survival when the group is cornered by a pack of Velociraptors and trapped by a sudden wildfire.
