A freak heatwave sends the temperature soaring on the remote island of Fara. The locals, including Dr Vernon (Peter Cushing) and novelist Jeffrey Callum (Patrick Allen), are left dazed by the rising temperature. When Callum is reunited with his former mistress Angela Roberts (Jane Merrow), the atmosphere becomes even more tense. It falls to Godfrey Hanson (Christopher Lee), another visitor to the island, to solve the mystery. The unbearable temperature is the result of a heat ray directed towards the island by creatures from another planet. As the spearhead of their invasion force materialises, the surviving humans are left at the mercy of the unstoppable aliens...

Night Of The Big Heat was the final collaboration between Christopher Lee, Peter Cushing and legendary director Terence Fisher. This digitally restored collector's edition features specially recorded bonus material with Christopher Lee and screenwriters Pip and Jane Baker.
