Ties itself up in knots with narrative complication so that by the time it comes to the dumbest of dumb climaxes you’re simply worn out. And having tied itself up in knots, it only escapes from the problem of a son coming to terms with a mother who’s a serial killer by providing him with the most unlikely of get-out-of-jail-free cards. And, actually, by the time you reach the conclusion you realize it’s really about nepo kids, one dumb as all get out and the other a chinless wonder.
Keeley Hawes as Julie the titular murderous mercenary is good value but that’s mostly because she curses like a defrocked nun and is as ratty as hell and her engagement with her estranged son Edward (Freddie Highmore) is like Lethal Weapon on speed.

So Julie, retired a decade and holed up in Greece, is pulled out of retirement because…she’s closest to potential victim Kayla (Shalom Brune-Franklin) …who is (it turns out) the unlikely girlfriend of unlikely journalist (of what? Rabbit Times?) Edward who is only (it turns out) interested in her because he’s been left a dodgy inheritance by his mysterious father (now deceased) and the trail of that leads to her family.
But not killing Kayla makes Julie the target of various other assassins, but rather than going about their job in discreet fashion by picking her off with a telescopic rifle they decide to barge in on a wedding and massacre everybody in sight in the hope a stray bullet hits her. Luckily though, that provides an opening for local butcher Luka (Gerald Kyd) to become her sometime companion.
Then we leap into a menagerie of subplots. Kayla’s cokehead brother Ezra (Devon Terrell) has mummy issues (she’s deceased, too, mysteriously committing suicide) which (it turns out) is the perfect way for another subplottee Marie (Gina Gershon) to enter the equation. After shagging him to pick his brains she (it turns out) is Edward’s long-lost aunt. Then there’s the mysterious letter, written on yellow notepaper (!!!) kept hidden in a safe by Kayla’s dad, billionaire tycoon Aaron (Alan Dale), which contains information so dangerous it could destroy his business.

But (aha!) someone knows the secret, Aaron’s tech expert Jasper (David Dencik) is blackmailing Aaron but is now on the run. Anyways, Kayla discovers the terrible secret which is that Aaron was initially funded by a dodgy arms dealer. To prevent that secret getting out, Aaron had him bumped off 30 years ago by (wait for it) Julie on her first solo killing mission.
Kayla is threatening to expose her dad’s secret though it doesn’t occur to her to just hand the exclusive to Rabbit Times chief investigative reporter Edward. Meanwhile, Ezra spends his time concocting barmy plans majoring in violence that all go south until his exasperated dad gives up all pretence of considering him as just the guy to run the business when the time comes.
Meanwhile, Marie (it turns out) isn’t Edward’s long-lost aunt after all – she’s (wait for it) his long-lost mum. And when Edward finds that hard to believe she kidnaps him and takes him to a stronghold. But (it turns out) Edward’s suspicions are correct.
There’s scarcely a minute goes by without someone bursting in with a machine gun or worse, so it’s no surprise that Julie and Luka (who’s proved himself handy with a meat cleaver) decide to invade the stronghold. And that sets up the preposterous finale.
Marie isn’t Edward’s birth mum at all but her dead husband was his father. Marie didn’t fancy all the messy things pregnancy did to a young beautiful body so they called in a surrogate. But Julie, in the way of Jason Bourne, had a conscience three decades ago when it came to kids and after knocking off Marie’s husband, in the absence of a bottle of milk or any other pacifier to soothe a crying baby, scooped up said infant (Edward).
Marie wants her revenge by having her not-son Edward kill his not-mother Julie. You couldn’t make it up. Yet someone did, presumably as the get-out-of-jail-free card so Edward didn’t have to worry about being the son of a serial killer.
And to show how grown up her is, Edward kills Marie. And as if this was Revenge of the Nepos, Ezra poisons his old man.
Kayla forgets all about exposing the nasty beginnings of her family company and Edward ignores the complications of the serial killer mum and they all (literally) sail off into the sunset.

The only good thing to be said about this is that it knocks Guy Ritchie off his throne as the King of the Preposterous.
