Wrap Party

A blackmail plot at the end-of-season wrap party for middling detective series Bankwood turns fatal - because another member of the cast has a plan of their own. The setting: a spectacular underground Masonic Hall beneath the City of London, with many tunnels, no phone signal - and only one way out. Unlike the programme, there are no killers or psychopaths, but a disparate group of people who all have a secret they'd rather stay hidden - and will go to extreme lengths to keep under wraps.
