Director/writer Leigh Whannell presents a vision of a Utopian future where technology is supremely ubiquitous. In that future, technophobe Grey Trace (Logan Marshall-Green) embraces an experimental computer chip implant named STEM after a mugging incident leaves him paralyzed and his wife dead. STEM proves to possess its own agency, making for an unpredictable ally in Trace's vendetta.
A brutal mugging leaves Grey Trace paralyzed in the hospital and his beloved wife dead. A billionaire inventor soon offers Trace a cure — an artificial intelligence implant called STEM that will enhance his body. Now able to walk, Grey finds that he also has superhuman strength and agility — skills he uses to seek revenge against the thugs who destroyed his life.
