Puppet Master

Louis Massina is revolutionizing the field of robotics. His technological wonders are capable of locating disaster survivors, preventing nuclear meltdowns, and replacing missing limbs. After one of Massina's creations makes a miraculous rescue, an FBI agent recruits him to pursue criminals running a massive financial scam - and, not coincidentally, suspected of killing the agent's brother. Massina agrees to deploy a surveillance bot that uses artificial intelligence to follow its target.

On Easter Sunday morning, the city of Boston is struck by a widespread and coordinated series of terrorist attacks: an explosion in the T, a suicide bomber at Back Bay Police Station, and heavily armed gunmen taking hostages at the Patriot Hotel. For robotics innovator Louis Massina, aka the Puppet Master, this is far more personal than a savage act of political terrorism. Boston is his city - and one of his employees, Chelsea Goodman, is among the hostages facing certain death.
