Little Brother

A savvy teenager named Marcus is well-versed in the workings of the networked world, and outsmarting his school's surveillance systems comes easily to him. But his life is turned upside down after a terrorist attack in San Francisco, landing him and his friends in a secret prison where they're interrogated by the Department of Homeland Security. Released but now living in a police state, Marcus takes matters into his own hands to bring down the DHS.
