66 million years ago, an asteroid is headed towards earth. All of the dinosaurs will go extinct. Most of the dinosaurs that is,  because two of them knew this was coming. They built a time dilation portal to escape extinction, but something goes wrong and they end up separated, with one of them thrown into a bunch of different dimensions. Can they find their way out?
