In the depths of space, a strange group of aliens is performing an evil experiment on a group of humans in an effort to find the existance of the soul. Every twelve hours, they change people's lives around to find if they will take on each others' characteristics. In other words: is a person more than the sum of their memories? Then one of their subjects gains the ability to resist their power, but can he stop the strangers in time? A well-known movie but I know few people who have actually seen this interesting film.
