P STORM is the fourth in the series of crime thrillers following ICAC cop Louis Koo as he tackles various tough assignments. This one stands out from the first three as it involves Koo going undercover in prison to bring down some corrupt guards and the like. The story is notably more action-packed than previous instalments with some solid fight scenes and shootouts to recommend it. I've always been a fan of prison movies and this one doesn't disappoint with the suspense inherent in the premise. Koo delivers his usual solid role and the supporting cast is enlivened by larger-than-life characters. No masterpiece, but watchable for what it is.
