One room. Four genius minds. The greatest enigma will
be how to survive.
Four strangers, who are all mathematicians, are invited to spend a weekend together where they will be challenged to solve a great enigma. Their mysterious host is only known to them by a pseudonym: Fermat. The room in which they find themselves turns out to be a death-trap that will crush them if they do not discover in time what connects them all and why someone might wish to murder them.
