However things grow complicated when he ends up falling for the daughter of his hit, especially after the deed is done and she begins to question who killed her father and why.

This puts her in the path of John and Lee Alberts, the two gangsters that hired Jamie, requiring him to protect his new love while also trying to avoid the two brothers.

[3] Flickering Myth gave the film two stars, stating that it "will probably prove to be quite popular with those into their British crime movies as it looks pretty good with some stunning wide shots of London in various different lights, and for Danny Dyer it’s something of a step up from his usual performance and will hopefully be seen as a defining moment for him, but otherwise Assassin is a little bit too underwhelming in the areas where it should have been stronger.
