Aaron Paul and Josh Hartnett play two astronauts on a mission in space. But fortunately for them, they get to still see their families, well sort of, with the use of doppelgangers. One of the two experiences a horrific tragedy with his family which leads to decisions the other astronaut would regret. Once you see what's going on, you'll probably agree it's a bit predictable. However the very ending there's a little curve ball twist moment which caps the episode off nicely.
If you're a Twilight Zone fan, you may notice (as I did) one astronaut is named Stanfield and the other is named Ross. In the TZ episode "The Long Morrow", the astronaut who ages by pulling himself out of hibernation is named Commander Stansfield. And lead astronaut in the episode "Death Ship" from season 4 is named Captain Ross. Maybe just maybe Black Mirror was paying homage to The Twilight Zone.
