There's the occasional bit of energy and flash to this geezery caper from director and co-writer Julian Gilbey, but it's let down by the Hollyoaks acting and humourless unbelievability. The film is allegedly based on a true story, the kind of true story which is probably mixed in with a good bit of urban myth, unverifiable crim legend and late-night Groucho Club anecdote; there is a faint resemblance to the plot of another London crime thriller, Paul Tanter's The Rise and Fall of a White-Collar Hooligan. Ed Speelers, Alfie Allen, Will Poulter and Sebastian De Souza play a quartet of chancers who run a scam blackmailing businessmen, honeytrapping them with prostitutes, then forcing them to hand over their credit-card details and PIN codes to let our antiheroes buy what they like for 24 hours before the card can be reported stolen. They wind up ripping off a sinister German gangster who threatens extreme nastiness unless he is paid back, so the crew head off to Miami with a plan to con a diamond company. Just occasionally, the story accelerates to a canter,and Gilbey works hard to deliver some bangs for your buck. But it soon collapses into cliches. "Plastic" just about covers it.
