Takedown

Summary: When a British Special Forces soldier goes rogue, carrying out an attack at a US army base in Syria leading to the death of two men, ex-MI5 controller Charlotte Button is hired to work out what his plan is and to take him down before he can carry it out. When the man returns to the UK it looks like the threat will be a lot closer to home. Charlotte puts her best man on the case - hitman Lex Harper. It's up to Lex to assemble a crack team and get to the soldier before he carries out what could be a massive terrorist attack. But Charlotte might require Lex's help with a more personal problem too.
