Gray (Logan Marshall-Green) and his girlfriend Aisha (Melanie Vallejo) have been in love for many years, and their relationship is very good. One day, Gray took Aisha to visit a scientist named Alan (Harrison Gilbertson), who designed the artificial intelligence chip STEM, which amazed Aisha. On the way back, the driverless car Gray and Aisha were riding broke down and took the two to a slum where thugs gathered. There, the two were attacked. Aisha was unfortunately killed, and Gray was severely injured and paralyzed. Full of pain and despair, Gray wanted to avenge his lover, so he found Alan and implanted the STEM chip into his brain. Under the control of STEM, Gray stood up again. What Gray didn't expect was that STEM's wisdom far exceeded his imagination, and he was also involved in a huge conspiracy.
