This is the heist scenario. You know, the big idea, the round up of talented villains, the trials and tribulations of the heist, followed by the spend, spend, spend.

The man who invented it didn't want it. The man who bought it didn't need it. The man who needs it doesn't know it. What is it? The answer to the riddle posed by Brian Reader (Larry Lamb) in the tense pub stand off with a group of youngsters I will leave to you.

In this based on fact robbery story, a mystery shopper (Matthew Goode) recruits four ageing criminals to break into the Hatton Garden Safe Deposit Company premises over Easter 2015. They not only steal multi million pounds in cash and jewels but also a much sought after box implicating a certain ex-CID policeman.

The heist is organised by an Eastern European crime family which obtains the required multi million pound jewel swag then melts into the background.

The Mystery Shopper escapes, but the older criminals allow themselves to be caught.

This is a slow retelling of the now famous robbery, with some anachronisms regarding the cars used in the film. Also, the shape of the hole changes, and never matches the real one as shown in the news footage of the day. There are obvious mistakes in the use of the break-in equipment.

I now know why my wheelie bins were stolen a few months back. They make convenient carriers for tools and loot on such escapades.

A pleasant tale told for the armchair criminologists. It lacks detail for the keen observer.
