Set in the very near future, this riveting thriller explores how technology and terror could transform civilization into a dystopian society of constant surveillance.

Reclusive, brilliant mathematician Stephen Ezard returns home to England to attend his brother Michael's funeral, an aid worker killed by a landmine in Afghanistan. After years of working in near-isolation in China, Stephen struggles to reconcile his carefully controlled world with a brother he did not know, in a police-state London he does not recognize.

He finds himself falling in love with his brother's widow, Yasim, and becoming the public face of the government super-database Total Information Awareness, a program with the ability to watch and record the actions and movements of every individual. Caught up in an international conspiracy, he must decide who, if anyone, he can trust.

Benedict Cumberbatch (Atonement) stars as Stephen, with Max Beesley (Hotel Babylon) as Michael, and Anamaria Marinca (Sex Traffic) as the beautiful and mysterious Yasim.
