Four mathematicians who do not know each other are invited by a mysterious host on the pretext of resolving a great enigma. The room in which they find themselves turns out to be a shrinking room that will crush them if they do not discover in time what connects them all and why someone might wish to murder them. ?Luis Piedrahita & Rodrigo Sopeña
