Hunted begins on Thursday 10 September on Channel 4, 9pm

The premise is simple: 14 ordinary people flee their lives and try to
live “off grid” for a month while evading capture. The hunters,
commanded by Lovegrove, begin with only the names, addresses,
photographs and dates of birth of the escapees, and attempt to track
them down.

In order to locate their targets, they are allowed to use all the
surveillance mechanisms available to the British security services
including CCTV footage (there are up to six million cameras nationwide),
automatic number plate recognition, as well as phone and email records.
