A fully automated robot RS1 that can be used to replace soldiers in combat was successfully developed and sent to Hong Kong for an exhibition. RS1 has great destructive power and is also very dangerous. Its existence makes many criminals salivate. Hong Kong special police officers Ma Qi (Feng Delun), Alan (Li Cansen) and Addison (Edison Chen) were ordered to protect the safety of RS1. Ma Qi and Addison had a very unpleasant past, which caused the two to have conflicts repeatedly during their cooperation. Kurt (Sun Guohao) is Addison's good friend, and his real identity is a genius hacker. Kurt hypnotized Addison while reminiscing about the past, manipulated him to turn on the switch of RS1 and input the escape program. RS1 caused a big commotion in the venue, causing countless casualties, and Addison was also listed as the number one wanted criminal and was pursued by the FBI. Addison knew that if he wanted to prove his innocence, he had to catch Kurt, who was currently missing.
