Two buddies, who have been friends since childhood, are the sole survivors of a global apocalypse which has drenched the world with toxins. They live in a geodesic dome on Earth. Ray (Sterling K. Brown) is a scientist who built the dome and oversees a hydrponic garden as their source of food. Billy (Mark Duplass) is the more emotional of the two. It comes as quite a shock to learn that he was once President of the United States and is responsible for the destruction of the planet.
Things have been going pretty well inside their orb until they notice a strange light approaching from outside. Then their last female fish dies, threatening their food supply. When one of the male fish evolves and develops female reproductive capacities, they have to deal with a new mystery. And that’s not the biggest one.
This film has many of the qualities of the typical “buddy film” – pleasant camaraderie, some bickering, some tender exchanges -- but it goes one step further. Ray and Billy’s friendship, it turns out, is not enough. They have to deal with impending death, gender fluidity, change, magic, and hope. As we learned from Jurassic Park, “Life finds a way.”
