Czech cosmonaut Jakub Procházka is six months into a space mission to investigate a mysterious cloud of dust and particles, called Chopra, lying beyond Jupiter. The Czech mission has arrived shortly before a competing South Korean mission. Jakub struggles with loneliness and misses his wife, Lenka, who has recently stopped talking with him after he left her and their unborn daughter behind to go on the mission.
Lenka sends him a message telling him that she wants to leave him, but Commissioner Tuma, Jakub's commanding officer, prevents it from reaching him, to prevent Jakub's mental state from worsening. Days later, still without news from Lenka, Jakub finds a spider-like creature with telepathic abilities inside a compartment of the ship. The creature, whom Jakub names Hanuš,}} wishes to understand humans better and to help Jakub with his loneliness.
Exploring his memories, Hanuš learns more about Jakub: his father was an informant of the state party and was killed when Jakub was young. He met Lenka, but often neglected her, being more focused on his career as a cosmonaut, going as far as leaving her when she suffered a miscarriage. After showing Jakub an implanted memory of the miscarriage, which Jakub was not present for, Hanuš, disappointed with humanity, leaves the ship, leaving Jakub distressed.
Jakub arranges with Petr, a technician and good friend of his, to deliver a message to Lenka, asking for forgiveness for his neglect. Hanuš returns after this, revealing that he's dying due to a parasitic infection that wiped out his entire species.
The two finally arrive at the Chopra cloud, which is revealed to be a leftover of the beginning of the universe and where every moment of time exists simultaneously. Hanuš leaves to die in space, but Jakub goes after him. Within the cloud, Jakub comes to the conclusion that he wishes only to be with his wife. She appears to him in a forest scene as a rusalka. Hanuš passes away due to the infection.
Jakub is rescued by the South Korean space vessel. Jakub and Lenka talk again, coming to terms with their relationship.
