Rescue Party (When the World Ends, #1)

A spaceship crew from an advanced alien civilization notices that Earth faces imminent destruction as its sun begins to explode. With time rapidly ticking down, the crew desperately searches a now-desolate planet for any possible human survivors.

This is a dramatisation of the very first short story written by one of the world's most prominent Science Fiction authors.
