This plays like a one-set, one-Act stage play that has been 'opened out' for the big screen. There are elements of just about every movie you can think of in the same genre and there's a certain amount of 'cheating' in the way that information it would be logical for the audience to know is withheld in the interests of plot twists. It's certainly well done and hooks from the opening sequence in which two of the principals first buy the material they will need for their plan to succeed and then utilise it in soundproofing and securing a room which will house a hostage. Where it perhaps falls down is in never allowing the world outside to intrude. A millionaire's daughter is kidnapped and two million demanded for her return yet at no time do we see the (presumably) worried father, the police (who, equally presumably) have made plans to monitor the exchange. Arguably the worst omission is the pick-up of the money which is never seen; instead the senior kidnapper returns to the junior and the 'victim' with the money and no signs of pursuit by the police. Though the acting is high standard from all three the flaws are just too glaring to overlook.
