In “New Mars”, a 19-minute film on DUST (May 21, 2021), people have been living in underground caves for eons on Mars, having migrated from Earth, which got destroyed. “They were spoiled.”
One day, men and women are assigned to each other as mates to go out into the terraformed world and repopulate it.
They’re each assigned to a farm with an earthlike Soviet-style building to live in.
They’ve been chemically treated to increase sexual attraction. All perfectly set up.
