In the near future, humanity has successfully colonized space and build a giant orbital station "Delta". Max is a repairman working on the station. After a disaster caused by a proton storm, he is left alone without his crew members, drifting into space. His space suit is broken, he is exhausted, and he lacks communication with people. But suddenly a dispatcher named Anna comes to help. She is the only one who can guide Max through difficulties and get him to the station.
