As John faces off with someone from his past, Dutch faces her own personal hell: trapped in a space elevator with a bunch of pompous Qreshis who start mysteriously dying around her one by one.
Killjoys follows a trio of hard-living bounty hunters - Dutch, John, and D'avin - taking on interplanetary missions, chasing and capturing deadly criminals throughout a distant system named the Quad. They have sworn amongst themselves to remain neutral during a bloody, multi-planetary class war that threatens to destroy the Quad. However, their own pasts and the events around them begin to draw them in deeper to this dangerous vortex of war.
