Early morning. Young girl Leah stands on the edge of the roof and prepares to commit suicide. At the last moment, she is pushed away from the edge by her housemate Sergei, who somehow inexplicably appeared on the roof at the same time as her. During the verbal skirmish, it turns out that Leah had planned the jump for a long time and is determined to bring the job to the end. Sergei, who, it turns out, was on the roof with the same intentions as Leah, is by no means so sure of the correctness of this act, but he also does not see other possible solutions to his problem.
