Planet of the Astronauts

Three astronauts return to Earth after a failed mission to Uranus and four years of being trapped in a black hole. They land in a deserted New York City and discover other astronauts, who tell them about the Covid-27 virus and its subsequent pandemic. The newly founded international alliance of astronauts, and the commander's love interest, aim to travel to Europe in search of an Italian doctor and his everlasting vaccine in order to save humanity.
