John Kennex is a police detective working in Los Angeles in the year 2048, a time when crime has increased dramatically and technological advancement plays a major role in public safety. During a catastrophic ambush early in his career, Kennex loses his partner, one of his legs, and much of his memory. After spending seventeen months in a coma, he returns to active duty with a sophisticated prosthetic limb, still carrying physical and emotional scars from the attack. His experiences have left him dealing with trauma, distrust of androids, and ongoing psychological challenges as he adjusts to life back on the force. Friendship and cooperation between humans and machines shape everyday life in his world, and law enforcement has adopted a policy that requires each officer to work alongside a synthetic partner.
