Conman Franky Four Fingers successfully turns another business, and now he has nothing left: to quickly sell off small profits in London, and then rush back to New York with a huge diamond for his boss. But no such luck. To steal such a pebble is still flowers, and berries - to try to take it away from under the noses of London crime bosses, next to whom American gangsters were not even close. Franky didn't have time to blink an eye, as he was involved in an enchanting story involving a pikey camp, a Russian arms dealer, promoters of illegal boxing matches and a psychotic mobster... It couldn't end well.
