The Puppet Masters is a 1994 sci-fi thriller directed by Stuart Orme. The movie is based on the novel of the same name by Robert A. Heinlein. The film begins with a group of scientists discovering an alien spacecraft in rural Iowa. They soon realize that the ship is carrying parasitic creatures known as "slugs" that attach themselves to human beings and take control of their minds.
The slugs spread rapidly and begin taking over people in major cities across the United States. The government commissions a team of top-secret agents called "The Corps" to combat the threat. The team is led by Andrew Nivens (Donald Sutherland), a veteran agent who has spent his entire career studying extraterrestrial life. His team includes his partner, Mary Sefton (Julie Warner), and a young recruit named Sam (Eric Thal).
The agents soon discover that the slugs are almost impossible to detect and are difficult to remove once attached. The team sets out across the United States, risking their lives to track down the source of the invasion. Along the way, they encounter a variety of obstacles, including skeptical military leaders and slug-infested civilians.
As the Corps gets closer to the source of the invasion, they face increasing danger from the slugs and their human hosts. Nivens becomes infected with a slug, forcing Mary and Sam to choose between killing him and potentially saving the Earth.
In the end, the Corps discovers that the slugs were sent to Earth by an advanced alien race that plans to colonize the planet. The team manages to stop the invaders from launching their final attack, but not before many lives are lost.
The Puppet Masters is a tense and thrilling sci-fi movie that poses questions about the nature of humanity and the threat of alien invasion. It received mixed reviews upon its release but has since become a cult classic.
