On his return to Britain, Jack is immediately sacked for his extraordinary behaviour in Pakistan. Not only this, but his wife has moved out, and Caroline has run away from the rehabilitation clinic. In Germany, Ulli believes he has trapped Helen and intercepts what he thinks is her heroin shipment. But Helen has double-crossed everyone, and the heroin shipment is actually bound for England. Fazal's wife Sabera has agreed to smuggle heroin for Tariq Bhut in return for a promise that he will secure her husband's release from prison. But some of the heroin leaks during her flight to Britain, and although the shipment is a great success for Helen, it causes Sabera's death.

Jack returns to Pakistan to sign the aid agreement. Encouraged by the lawyer Roquia, he presses further, demanding specific arrests before he will sign. His political pressure on the authorities to take more action against known traffickers results in the destruction of a shanty town area of Karachi. Unknowingly, this brings about Fazal's downfall, who is set up as the fall guy by Tariq. Fazal is arrested and thrown in jail. Jack goes back to the North West frontier and finds himself in the middle of a personal crisis, having lost direction for the first time in his life. He smokes opium with a Pathan guide, and refuses to sign the aid agreement on his return to Karachi, causing uproar. Helen travels from Hamburg to Pakistan to agree a deal with Tariq Bhut, but she must prove herself worthy of his trust.

Jack Lithgow is still under heavy pressure from his job at the Home Office, but worse, his daughter takes a drugs overdose and is hospitalised. He books her into an expensive residential clinic to try and get her off heroin. Fazal accompanies Tariq on his visit to the North West Frontier of Pakistan to buy part of the opium crop. He is then left to oversee the conversion of opium into heroin at a remote laboratory. But the chemist and Tariq argue about the price, and Tariq returns with armed men. To test Fazal's loyalty, which he is beginning to doubt, Tariq orders Fazal to kill the chemist. Fazal refuses. Karl's trial begins in Hamburg. Evidence hinges on the testimony of Ledesert, the supergrass who was caught by Ulli and Dieter. Helen tries to get Ledesert assassinated to stop him testifying, but the plan goes badly wrong.

Fazal has been promoted to Tariq's chauffeur. A lawyer, Raquia, is trying to get the big time drugs trafficker arrested.

Jack Lithgow returns to Britain from Pakistan to find that his daughter, Caroline, has been arrested on heroin charges after a student party. Jack confines her to the family home and watches her night and day until he thinks she's off the drugs - but Caroline has been fooling him. Back in Germany, Helen learns that her husband, Karl, is still owed a lot of money by his dealers, which she sets out to recover, but in a massive police raid Karl's entire network is arrested. The situation seems hopeless; Karl is formally charged with trafficking and a trial date is set. Any chance of recovering the money has now been lost. In Pakistan, Fazal travels to Karachi in search of work and becomes increasingly involved in the heroin empire of Tariq Bhut, a wealthy and influential drug trafficker.
