Radiant Terminus takes place in a Tarkovskian landscape after the fall of the Second Soviet Union. Most of humanity has been destroyed thanks to a number of nuclear meltdowns, but a few communes remain, including one run by Solovyei, a psychotic father with the ability to invade people's dreams - including those of his daughters - and torment them for thousands of years. When a group of damaged individuals seek safety from this nuclear winter in Solovyei's commune, a plot develops to overthrow him, end his reign of mental abuse, and restore humanity.
