What if 'Trapped in Time' talks about all of us? An investigation of the most famous loop in cinema. Critics Santiago Alonso and Isabel Sánchez publish an essay on the comedy starring Bill Murray whose legacy has continued to gain cult status.

Prisoners of the Loop is made up of a first part dedicated to the production of the film, a second about the literary and cinematographic background, and a third where the authors dialogue about other time loops. The filmwriter of Atrapado en tiempo, Danny Rubin, says that the idea for the story came to him from the novel Lestat the Vampire by Anne Rice.
