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.
Unfortunately the movie Fermat's Room is not yet available on HBO Max.
