Two astronauts, the American Commander Rachel, and Victor, her Russian counterpart, are at the end of a long space mission. They have discovered alien life on the distant planet they’re living on, but have not successfully devised a way to get it safely back to Earth. After each collection attempt on the planet surface, back in their makeshift, tent-like living quarters, they scan each other for exposure to the lifeforms. Frustrated with the thought of leaving empty handed, Victor secretly infects himself with the alien just prior to heading back to planet Earth. At the final moments before their departure on the long journey back, he waves off Rachel’s final attempt at the scanning protocol, and it is clear – they won’t be going home alone.
