What Happens in Puppet on a Chain: Full Plot Summary

The whole story of Puppet on a Chain (1970) explained, from the opening scene to the final frame: every key event, every twist and what it all adds up to. Read it as a quick recap before the sequel, to check a scene you missed, or to finally understand what really happened.

After three hippie drug-dealers are murdered by Jimmy Duclos, the assassin, in a house in Los Angeles, the U.S. government sends special agent Paul Sherman to track down the Dutch source of heroin fueling the drug war.

On arriving at Amsterdam's Schiphol Airport, Sherman witnesses the grim outcome of a planned meeting: Jimmy Duclos is shot dead by the assassin, signaling that the drug network has eyes inside the city.

Amsterdam's chief of police, [Colonel De Graaf], is openly hostile to American interference, while Sherman’s direct contact, [Inspector Van Gelder], is more cooperative, partly because his niece, Trudi, has suffered brain damage from a heroin overdose years earlier.

Sherman makes contact with Maggie, a deep-cover agent from Washington. He is then followed around Amsterdam by the assassin, indicating that the drug dealers have someone on the inside. Sherman manages to evade and later confronts the killer in his hotel room, where a fatal struggle ends with Sherman accidentally killing him.

Sherman meets Astrid Lemay, Astrid Lemay, and her drug-addicted brother, George Lemay. George dies of an overdose, and Astrid herself is murdered in a brutal turn of events.

During a perilous chase, Sherman is attacked by a man on a boat and shoots him dead. Meanwhile, Meegeren, the drug lord Meegeren, murders Maggie by hanging her from a chain and then takes Sherman prisoner. Meegeren slips away aboard a speedboat, and Sherman pursues him on another craft. The pursuit ends when Meegeren’s boat crashes and is consumed by fire.

The chase leads to a warehouse run by Morgenstern, where the drugs are distributed. There Sherman meets Van Gelder and his niece, Trudi. A shootout reveals the complicity of Trudi and the broader gang, leaving Trudi dead and Sherman wounded. Van Gelder makes a desperate attempt to flee, but Sherman ends his life, bringing a grim conclusion to the Dutch side of the operation.

Q1

Why is Inspector Van Gelder cooperating with the American agent?
