Science fiction movie. A quite underrated film, as it has a special concept that is somewhat reminiscent of Inception and other similar films or even much older ones like Lawnmower man (1992), but with a different idea. So it is about the development of programmable biological substances in the form of ophthalmic solution, which put the user to sleep for a few seconds and during this time he lives experiences as real through programmed dreams. These scenarios each have a specific theme, e.g. Skiing in a snowy landscape, holidays on an exotic island, etc, but they have the flexibility for the human brain to freely choose the evolution of the scenario. Such technology could have infinite possibilities beyond a simple break. The deepest desire of the programmer, however, is to be able to develop it, so as to wake up her brother who is in a coma. Everything changes when there is a lethal accident with these substances and they force her to apply this technology to prisoners to save the company, but also to try it with such a scenario of prison on herself. What is reality and what is imagination? A very original script with multiple plot twists and quite well made as a whole. It could have had more action, effects and suspense, but it has done quite a good job overall and is definitely among the recommended films in the genre.
