The Fixer is an action-packed, high-octane series that asks whether operating outside the usual parameters of the law - under the pretext of protecting it - can ever be justified.

In the shadowy world between right and wrong, John Mercer is a modern-day gun for hire, beholden to his sinister master but not the boundaries - moral or otherwise - of the law. Released from prison unexpectedly early, Mercer is introduced to Lenny Jameson - a police officer 'retired on grounds of ill health'. Jameson makes it clear to Mercer that his freedom comes at a price - he must remove an untouchable criminal who has recently dispatched a senior police officer to an early grave.
