There has been a rash of attacks against humans by promotional sample robots. Kusanagi's team rounds up robots of that same model line, and they learn that they all share a common trait. Batou and Togusa head to Hanka Precision Instruments, where they are made, to determine what is behind the attacks. 

Kusanagi and her boyfriend are rushed to the hospital after being attacked without warning. They suspect Toru Soma, a terrorist that Kusanagi has a history with. Kusanagi and Togusa leave the hospital, and after leading their pursuers on a chase, they find themselves in a fierce battle against an armed group in an abandoned factory.
