British doctor Raj Patel puts his own life on the line to treat the injured in war-torn Syria. His medical skills help casualties survive against all the odds. But Raj needs to rely on a completely different set of skills when he is taken in a dangerous case of mistaken identity. A Navy SEAL has gone rogue, selling his skills to the highest bidder as a professional assassin. Ryan French no longer cares who he kills so long as the price is right. His former bosses want him taken down, but they're not prepared to get their hands dirty so they need a Brit to do the job. The target - the Prime Minister. The assassins - hard-bitten jihadists with nothing to lose. The only man who can stop them? Dan "Spider" Shepherd. But Shepherd's reputation is also on the line - he helped get one of the jihadists into the UK during the final days of the War in Afghanistan. Murderous jihadists have been crossing the English Channel, passing themselves off as asylum seekers. MI5 have been keeping them under surveillance, but what starts as a simple takedown goes badly wrong and dozens of innocent civilians are killed in the heart of London.
