The Syndicate (2012)

When wannabe serial killer Rhys accidentally strays onto seasoned killer Nathan's territory it seems his quest for murder will be a short one. However, Nathan is part of a family of killers and, until recently, had killed in partnership with his brother Jamie. After losing his brother in a car accident, Nathan cannot adjust to working alone and Rhys - young, inexperienced and eager to learn the business - evokes the big brother in Nathan. When Nathan agrees to take Rhys under his wing and teach him the tricks of the trade, it seems the family is once more complete.
