The Killing Machine sees Nick Helm play happy-go-lucky human car crash Sam Miller, who turns up at the boxing gym with a simple dream: to become a killing machine. And it looks like reluctant, down on his luck personal trainer Donny Day is just the man for the job, while fellow trainer Aled doesn't think he's up to the challenge.

The Killing Machine is a buddy comedy about friendship, standing up for yourself and bringing the pain.
