Answer the following question: Information:  - Cube is a Canadian psychological thriller horror film series . The three films were directed by Vincenzo Natali , Andrzej Sekua , and Ernie Barbarash respectively . All three films are based on the same premise : there is a gigantic , mechanical , cubical structure of unknown purpose and origin , made up of lots of smaller cubical rooms . Each of these rooms has six doors , one on each face of the cube , which lead into adjacent , identically decorated rooms , only differing by colour . Some of these rooms are `` safe '' , while others are equipped with deadly booby traps such as flamethrowers and razorwire . In some cases it is possible to detect a trap by throwing an object into the room first , although this method is not always reliable due to the trigger mechanism of certain traps . In each case , a group of strangers awakens in this mysterious structure , without any knowledge of how or why they are there . In order to escape from the prison , they must band together and use their combined skills and talents to avoid the traps and navigate out of the maze , while also trying to solve the mystery of what the cube is and why they are in it . However , the pressure of being in the Cube generally turns one of the prisoners into a homicidal maniac who preys on the others .
