In 2032, a crewed expedition to Mars discovers a mysterious egg buried under the planet's surface and brings it to their ship, the SC-37. While the astronauts are away, the egg hatches, releasing a crystal and a slimy alien creature. The astronauts conduct experiments on the crystal and the alien, and are soon killed when their air supply is shut off.

Two months later, the SC-37 is intercepted by the space station L-5, which subsequently is destroyed by a malfunctioning neutron reactor. A ragtag repair crew escape aboard the damaged ship, and the dire situation forces them to work together despite their differences. The crew of five conclude that they lack the supplies necessary to return to Earth or await rescue, and decide to stop at a pair of supply stations to remedy this. Meanwhile, the alien hides in the engine room and quickly begins killing the crew. Soon, only two, Roger Campbell and Dr. Adrian Kimberly, remain. As Roger and Adrian lock the alien out of the bridge, it retreats back to the engine room with the crystal. Roger and Adrian find data from the original crew's experiments in the ship's computer, Bernice, indicating that the alien rapidly matures and grows in intelligence, while the crystal is an advanced computer the alien uses when confronted with a problem. Using the crystal, the alien hacks into and takes control of the ship, cutting off their communications and tricking another nearby ship into believing SC-37 does not require rescue. During a subsequent meteor storm that endangers the ship, the alien uses the crystal to project a force field until the storm passes. Roger is forced to enter the lab to retrieve a crate of rations, but when he returns to the bridge without threatening the alien, it lets him go. Soon after, the alien begins reading data on the evolution of the human race and a Bible stored in Bernice's memory.

Roger and Adrian decide to continue on to the first supply station, Alpha-7, but Bernice informs them that they will need to repair the engine for this to be feasible. Realizing they must confront the alien, they go the engine room, where it reveals itself to them. Much to their shock, it apologizes profusely for its actions, claiming that it was killing in self defense until realizing that humans were not as dangerous as it first thought. Identifying itself as GAR, it surrenders control of the ship back to Roger and Adrian, who forgive it and strike a bargain: after they reach the safety of Alpha-7, they will give SC-37 to GAR so it can return to its home planet. The trio work together and repair the ship, quickly forming a friendship with each other despite their initial conflict.

SC-37 docks at Alpha-7, and Roger helps GAR load rations in preparation for its voyage. However, a gravity tunnel soon opens; this anomaly can help Roger and Adrian return to Earth, but they must immediately depart aboard the SC-37 to make the trip. GAR realizes that it must part ways with the humans and thanks them, saying that it will always cherish their brief time as friends. Bidding them a sad farewell, GAR uses the crystal to convert Alpha-7 into a ship and sets off for its planet, while Roger and Adrian finally make it back to Earth.
