Puppet on a Chain (film)

Plot

After three hippie drug-dealers are murdered by "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 that is causing the drug war. On arriving at Amsterdam Schiphol Airport, Sherman witnesses an agent, Jimmy Duclos, who was there to meet him, shot dead by the assassin. 
Sherman is originally from the Netherlands, but it is clear that Amsterdam's chief of police, Colonel De Graaf is unhappy with having the Americans interfere in Dutch affairs. However, Sherman’s direct contact, Inspector Van Gelder is more cooperative, since his niece, Trudi, suffers from severe brain damage caused by a heroin overdose eight years earlier.
Sherman makes contact with a deep-cover agent from Washington named Maggie. Sherman is then followed around Amsterdam by the assassin, indicating that the drug dealers have someone on the inside. Sherman gets away from him and later confronts him in Sherman's hotel room, where Sherman accidentally kills him.  
Sherman meets Duclos' girlfriend Astrid Lemay and her drug-addicted brother George. Soon after, George dies of an overdose and she is murdered. Sherman is attacked by a man on a boat and shoots him dead. Drug lord Meegeren, who had killed Astrid, then kills Maggie by hanging her from a chain (although in the book she is pitchforked to death by the Dutch women in the courtyard) and holds Sherman prisoner. Meegeren leaves on a speedboat. Sherman escapes and follows him on another speedboat. The chase ends with Meegeren accidentally crashing his boat and it being destroyed by fire. 
Sherman and a colleague arrive at a warehouse (run by Morgenstern but without his partner Mugenthaler who only appears in the book) where the drugs are being distributed. There he meets Van Gelder and his niece. He finds out that they are part of the trafficking gang and that Trudi had been faking her mental disability. A shootout leaves Trudi dead and Sherman wounded. Van Gelder tries to escape, but is killed by Sherman (again a discrepancy in that he falls to his death in the film but is skewered on a hook in the book).

Production

The film was shot on location in the Netherlands and at Shepperton Studios. 
The famous boat chase sequence was performed by Wim Wagenaar and directed by Don Sharp who was specifically hired to do it. Once he completed that sequence he was hired by the producers to reshoot additional sequences. Sharp:
The chappie who directed originally [Geoffrey Reeve, who died in 2010] has gone on to produce some nice movies, and before this he had a good career in shooting commercials. And he’s a talented man. But he didn’t have a story sense then, as a director, and he and his camera operator, each set-up, you know, a sequence that looked like part of a television commercial and wasn’t there for the drama of it, or just to let the audience know what was happening. And therefore I had to take parts out of, for example, a nightclub sequence. Seventy-five per cent of it was fine; only when it came to the dialogue bits between them did I have to go in and reshoot it, because it just didn’t make sense – to shoot a couple of really good, important dialogue lines to do with the plot in a shot between the legs of a dancer . . . That wasn’t exactly it but I mean that sort of thing, you know. It was done for a visual effect.

Reception

Sharp said the film went on to make "a mint of money" and claimed in 2007 he was still getting royalties from it being shown on television.
The Monthly Film Bulletin called it a "singularly unappetising piece of work."
