The film features a character named Commander Mills, a pilot and explorer from before the time of mankind. Mills agrees to pilot a two-year mission in exchange for enough money to afford a life-saving medical procedure for his daughter, Nevine. However, when asteroid debris kills the other passengers, Mills is stranded on a Cretaceous-era Earth. He contemplates whether to send a distress signal for help, but after discovering the only other survivor, a girl named Koa, he commits to saving her from the planet's many dangers. The film appears to be an action-adventure story set in a prehistoric time period, with themes of survival and the lengths a father will go to save his daughter. The inclusion of a survivor who does not speak English adds an additional layer of complexity to the story, as Mills must find a way to communicate and work together with Koa to overcome the dangers of their surroundings. An astronaut crash lands on a mysterious planet only to discover he's not alone.
