Futuristic scifi, where remnants of the human civilization has taken a desperate attempt to relocate to a nearest hospitable planet, since Earth is doomed. All this is done with the bare minimum of technological know how and safe to say, it doesn't go too well. Space ships used to relocate the human populace, and the equipment to start over, land on the surface of the new planet, not all succesfully. There are ships that landed some distance away, others outright crashed, with few survivors. Other ships fates are unknown as connections are severed due to system malfunctions or unknown disturbances in the atmosphere. Surviving populace has to make due with what they have got and make a life in the remains of the ships that brought them there and try to make some sort of future.
Generations forward, there is life evolved around the old wreckages and societies have taken root. With scarce resources humans have put the little what they have brough, and what survived the crash, to use and else they have taken from their surroundings. With what little people have got, they have had to cut back all the unnecessary and unavailable. If the passengers had little clothing items with them, it was not enough even for the generation after them. But new generations adapt, as they are born into the life on the planet. Clothes are reserved for hazardous jobs, that being their sole purpose, protection.
That would be the premise and background, but the story could be something about communication systems firing up suddenly and something is heard, that prompts the need to send an expedition to see where the signal is coming from. And the story starts to roll forward once they find it.
