PART 1 - Scene 1 - Earth Cargo Vessel C7X9

It is the year 5005. Earth cargo Vessel C7X9 flies through the Second Scarlet Nebula, carrying a newly developed fusion reactor heading to Earth. This fusion reactor will help power a new space rocket to blast deep into the edges of the universe and expand mankind's understanding and journey in space. Once the ship has finished fueling up on a nearby planet, something gets aboard. And the crew begin dying out. When the TARDIS lands onboard, the Doctor, Nyssa and Tegan must stop whatever has got aboard from killing off the crew and help the reactor get to Earth safely. But is the creature really that bad?
