Fifteen years after its last contact with our world, a space freighter known as the Flying Dutchman requests permission to dock at a remote moon base. This mysterious ship carries liquid protons: a power source essential to the survival of Earth’s population. But before the precious cargo can be delivered, the base is ambushed by galactic terrorists who seek to destroy the new form of energy and issue a death sentence to all of humanity.
