BBC scifi drama serial The Monsters saw newlywed John Brent (William Greene) get caught up in a sinister mystery whilst staying in a small hotel in the North of England.
When a body is discovered in a lake that locals think may contain a Loch Ness style sea monster Brent begins an investigation. He quickly tangles with the strange Professor Cato who has his own fleet of mini-subs in the lake. There also may very well be real monsters in the lake too.
Obviously inspired by the whole Loch Ness Monster legend, director Mervyn Pinfield was a regular helmer on Doctor Who during its early years.
