Traffik

Jack returns to England utterly changed by his downbeat experience in Pakistan, with his career and family life in ruins as he is forced to resign his post, as well as struggle to help Caroline and get her into a rehab program before it is too late for her. Back in Pakistan, Fazal's wife, Roomana, goes to work for Tariq to secure her husband's release from prison in which Fazal decides to resort to drastic steps to get out of the drug making business for good. In Germany, Ulli prepares to intercept Helen's first shipment of heroin from Pakistan just as she works behind the scenes to secure Karl's release from jail so he can resume his drug trafficking business.

Jack returns to Pakistan to press the arrests in exchange for the British aide agreement which sets off a chain of events with devastating consequences for Fazal. Meanwhile, Helen also travels to Pakistan to do business with Tariq for another shipment of raw opium to Germany. But Tariq asks her to prove her loyalty to him first by trying to smuggle heroin with her back to Germany, while Ulli, still reeling from the murder of his partner, becomes determined to nail Helen who proves to be just as slippery and dangerous as her imprisoned husband.

In England, Jack confronts the mounting conflict between his political and personal lives as Caroline's drug problem becomes more out of control and his advisers tell him that the war against drug trafficking is unwindable. In Pakistan, Tariq brings Fazal to one of his remote heroin making laboratories where he tests Fazal's loyalty. In Germany, Helen launches her own counter-offensive against the police to destroy their case against her husband as Karl's trial for drug trafficking begins.
