British crime caper starring Bill Nighy and Emily Blunt. Victor Maynard (Nighy) is a lonely, uptight middle-aged mummy's boy who also happens to be a lethally efficient professional hitman. His last assignment before he retires is to take out con artist Rose (Blunt) for gangster client Ferguson (Rupert Everett). But finding himself increasingly attracted to the bold and beautiful Rose, Victor is unable to complete the job, and instead ends up trying to save her and delivery boy witness Tony (Rupert Grint) from the murderous intentions of his less-than-happy client.
