Dredd has been posted to Luna-1 for a 6-month stint as Judge-Marshal there. But, apparently, not everyone is happy to see him.
Dredd is nominated for as 6-month stint as Judge-Marshall of Luna-1, the Judge in charge of all law enforcement on the Moon. He refuses Walter, his robo-servant, permission to go along, but Walter smuggles himself on board anyway. As Dredd's shuttle approaches Luna-1, a missile fires at them, but Dredd causes it to detonate harmlessly against a cargo container. Later in his quarters, a robot tries to kill him, then self-destructs when questioned.
