ABC Weekend Television, who commissioned the show, broadcast it in its own regions four days later on Saturday 20 November 1965.

Mrs Peel visits the distillery, whimsically named Grannys Groggs, and finds the man in charge, Dr. Sturm, very unfriendly and quick to get rid of her.

They report their findings to a top meteorologist, Sir Arnold Kelly, who has arrived in the area and is quite incredulous and is convinced the equipment is faulty.

He tastes more wine and in doing so hears the sound of rain and sees a locked room, evidently full of ice.

Mrs Peel is held at gunpoint at Jonah's barn and taken to the factory and placed on the high tech wine press machine to force her to tell them what she knows.

They discover the body of Kelly and overhear Dr. Sturm talking to Mrs Peel about his plans through the vent to the distillery and that he intends to sell his rainmaking device to a military nation of the highest bidder and describes it as the greatest weapon since the atomic bomb, a "great flood".

Steed and Jonah enter the distillery through the vent when the doctor departs, and free Mrs Peel from the machine.
