"Hello, Earth. Hello, Earth. This is Commissioner Simmonds returning home after 75 years."
A Kaldorian spaceship en route to Earth crashes on the Moon and the Alphans find a crew of six on board in suspended animation. Their attempt to revive the crew accidentally kills one, but the surviving Kaldorians are understanding and a peaceful cultural exchange takes place. Koenig proposes that one Alphan could accompany the Kaldorians to Earth in the now vacant casket, and Captain Zantor agrees to the plan, stipulating that the chosen Alphan will have to be tested for compatibility with the Kaldorian suspended animation technology. The computer is set the task of choosing the one person who will return home, but Simmonds takes matters into his own hands, breaking into the power station and threatening to destroy Alpha unless he becomes the Kaldorians' passenger.
