When psychologist Chris Kelvin is asked to investigate the unexplained behavior of a small group of scientists aboard the space station Prometheus, he is shocked by what he finds upon his arrival. Kelvin discovers that his close friend, Gibarian, the mission's commander, has committed suicide. Also, he finds out that the two remaining scientists onboard are exhibiting signs of extreme stress and paranoia, seemingly caused by the results of their examination of the planet Solaris. Soon, Kelvin too becomes entrapped in the unique planet's mysteries. Solaris, somehow, presents him with a second chance at love and entreats him to change the course of a past relationship that has caused him overwhelming guilt and remorse. But can he really revisit the past and alter the course of events? Or is he fated to repeat its mistakes?
