Three researchers work on a paleontological project focusing on two dinosaurs: one fictional, the one created by special effects genius Ray Harryhausen for the film The Valley of Gwangi (1969); the other real, the Concavenator corcovatus, whose remains were discovered in 2003 at the Las Hoyas site, in the province of Cuenca (Spain), very close to where the filming took place.

In the late sixties, Spanish cinema began to produce a huge amount of horror genre films: international markets were opened, the production was continuous, a small star-system was created, as well as a solid group of specialized directors. Although foreign trends were imitated, Spanish horror offered a particular approach to sex, blood and violence. It was an extremely unusual artistic movement in Franco's Spain.

There’s only one person who so accurately personifies movie magic in the history of film, and that man is special effects maestro Ray Harryhausen. Focusing on the man behind the landmark effects on films like Clash Of The Titans, One Million Years B.C., Jason And The Argonauts and many more, this in-depth film features interviews with the great man himself, and with an array of animators and directors influenced by his work including Guillermo del Toro, Peter Jackson, Nick Park, Terry Gilliam, James Cameron and Steven Spielberg. The film also features unseen footage of tests and experiments recently uncovered.
