Would you ever cross the line? Two law students at Teesside University didn't think so, until one night their flatmate is involved in a violent incident. They make a decision to help him, and in doing so they compromise everything they once held sacred and embroil themselves in the world of Jamaican Yardies. Detective Inspector Harry Davis suspects that the Yardies are taking over the drug trade in Middlesbrough and his instincts tell him that the students are involved. Now the students must ask themselves: how well do they really know their flatmate's?
