With terrorist attacks in Britain causing political unrest across the country, Matthew Collins and Hope Not Hate fear a unhappy, racist reaction from the British far-right.
Forced to flee the UK and go into hiding in the 1990's when he became a mole from within the BNP, Matthew Collins returned to Britain to make a new life for himself.
The drama focuses on Collins and his work to stop the radicalisation of young white men before it begins.
