I'm not usually a fan of Guy Ritchie type films, but this was really quite enjoyable.
4 gangsters are locked in a crypt with a coffin which they are guarding until "Gordon" the big Boss arrives. They are later joined by a junkie and 2 more of the gang plus their lawyer.
Why they are all there becomes clearer and we hear about each of them, most of them despicable in their own way.
To further complicate the issue, some of them are convinced a vampire is preying on them too.
The body count rises.
There is a twist at the end which I never saw coming and, for a change the ending was satisfactory with everything explained.
