Jack Collins (Milo Gibson) is an unstable, world-weary ex-Navy Seal who tracks US’s most-wanted and terrorist targets under the auspices of CIA outsourcing. His handler for the CIA, Leigh (Blade Runner 2049’s Sylvia Hoeks) offers him a job, despite the apparent PTSD Jack’s been suffering and the other mental issues that assail him.

He’s dispatched to London (on what sounds like the premise to a Mission: Impossible film) in order to take down a rogue CIA operative named McKnight (Elliot Cowan) before he procures a nuke from Russian gangsters.

Jack’s assigned a team, in the form of operatives-for-hire Brennan (William Fichtner) and Samuelson (Gbenga Akinnagbe). Once in London, the group meet CIA compatriot Deighton (Joseph Millson) and it’s Deighton’s wobbly morality and possible connection to McKnight and his ‘is-he-or-isn’t-he-about-to-cross-everyone’ persona that leads to more violent shenanigans across London, in pursuit of McKnight and the warheads he’s trying to snarf.

There are double (and triple) crosses aplenty as Jack and Deighton continually lock horns and tread the well-worn path of bromance turned sour grapes.

It’s hardly an original format: the battle-weary warrior, the ‘Ronin’ looking for an end to the pain of existence. We get it. Writer/Director Matthew Hope is a dab hand at directing low-budget action sequences and on that front, if shoot-outs are your bag then there’s a fair bit of that to enjoy here. Other than applauding the filmmakers for wringing every drop from an all-too-obviously small budget, there’s little else to recommend this, except the sharply acidic William Fichtner, a hardened veteran of Hollywood supporting roles; he’s incapable of being anything less than enjoyable. As the lead, Gibson is unabashedly riding his surname’s coat tails (and his physical similarity to his dad) but physically, he’s got the goods, it’s just the underwritten script that leaves him – and the rest of the cast – twisting in the wind.

Overall, the fight choreography and action sequences are deftly executed but the brutally ‘by-the-numbers’ scripting, coupled with a considerable lack of character depth or humour, just annihilates any joy that could be derived from the film.
