While mainland Britain shivers in deepest winter, the northern island of Fara bakes in the nineties, and the boys at the Met station have no more idea what is going on than the regulars at the Swan. Only a stand-offish visting scientist realizes space aliens are to blame.
Unfortunately the movie Night of the Big Heat is not yet available on HBO Max.
