Synopsis: Master Detective John Simon and his android friend Lucas George are back, as the tough, streetwise fifteen year veteran of the Kansas City Police Department with a healthy disdain for the encroachment of modern technology pairs with KCPD Academy's first android graduate. When a string of unusual burglaries leads them to a warehouse of explosives, the partners soon find themselves and their friends in mortal danger as they uncover a plot by domestic terrorist to blow up a major tourist site somewhere in the city. Meanwhile, Lucas struggles for acceptance from those frightened by his superior abilities and skills within the department. When bodies start piling up, including two of their own, it's a race against the clock to track down and identify the terrorists and stop them before it's too late. With a task force that pulls in the FBI, the ATF, and other Federal agents, a massive search and investigation unfolds and his daughter Emma's best friend's father, a sax player, may hold the key to unraveling it all. But will he talk before it's too late?
