The lead female Coelophysis stalks a herd of Placerias, looking for weak members to prey upon. She faces food scarcity during the dry season, competition from other predators like the female Postosuchus, and the threat of cannibalism within her own species as Coelophysis begin to cannibalize their young. Despite these challenges, she survives through the dry season until the arrival of the wet season brings relief.

A male cynodont resides in a burrow with his family, surviving the harsh conditions of the dry season. He and his mate manage to produce a new clutch of eggs by the end of the episode, indicating successful reproduction despite environmental pressures and predation risks.

The female Postosuchus is one of the largest carnivores in the Triassic setting and attacks the Placerias herd, wounding one individual and causing the herd to scatter. This predation event adds tension and danger to the ecosystem portrayed in the episode.

The arrival of a migrating herd of Plateosaurus at the episode's end foreshadows the dominance of sauropods after the Triassic–Jurassic extinction event, signaling a major shift in dinosaur evolution and ecosystem dynamics.

Old Grande, a large dinosaur character, is shown performing osteophagy—eating bones to obtain minerals to help heal an injured leg. He also uses seismic communication to locate a female dinosaur, demonstrating complex behaviors like healing and communication that add depth to the portrayal of dinosaur life.
