Would you ever cross the line? Two law students at Teeside 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 hold sacred and become embroiled in the world of Jamaican Yardies. Detective Inspector Harry Davis suspects that Yardies are taking over the drug trade in Middlesbrough and his instincts tell him that the students are involved. Can they lead Davis to the gang boss? Now the students must ask themselves: how well do they really know their flatmates?
