As a Scottish person born and bred and one who visits the loch frequently and a lover of all things Nessie, I was pretty underwhelmed by this. It's a short film about the Nessie hunters and media circus that have followed the quest for the monster for decades. All the usual suspects are here. There's nothing about the monster or the actual investigations, it's more about the people behind the searches. They had an actor playing Frank Serle, possibly the most notorious Nessie hunter of them all. He died years ago so I'm not sure why this was included, it didn't really add anything as there was interview footage of him while he was alive. There's nothing new in this film or anything that can't be found by searching on YouTube. Pretty lacklustre.
