John Mercer (Andrew Buchan, who starred in Party Animals and Jane Eyre) is a former member of the Special Forces serving a double life sentence. He is released from prison unexpectedly early and introduced to the shadowy Kenny Jameson, a police officer retired on grounds of ill health.
Mercer realises his newfound freedom comes at a price. Jameson pulls together an unofficial operation with a single brief – to remove untouchable criminals from society.
Mercer must use the skills he learned in the Special Forces to execute a series of discreet hits.
To help him complete each mission, Mercer is introduced to his new colleagues who include Calum McKenzie (Jody Lee Latham), a petty thief whose main interests are girls, drugs and music.
Things are complicated by the final member of Jameson’s group – the sharp tongued but seductive Rose (Tamzin Outhwaite).
An ex-copper forced out of the police by scandal, she has always used her sexuality as her primary weapon and is more than a match for Mercer.
The gang operates outside the parameters of the law and is at odds with the world but when it comes to fulfilling its mission it is lethally effective. They are the solution. Mercer is the fix.
