Killjoys follows a trio of hard-living bounty hunters – Dutch (John-Kamen), John (Ashmore) and D’avin (Macfarlane). Working for the Reclamation Apprehension Coalition (Rac), they work in a four planet-and-moon system known as the Quad. Taking on warrants to apprehend people or property, Rac Agents are given high authority by their agency. As part of their job, they swear to remain neutral in conflicts and owe no allegiance to any system, government, or other organizations. With their pasts coming back to haunt them, the trio will have to work hard to keep themselves, and their friends, alive.
