Three guests in a luxury hotel. The highly respected managing director of a computer company, an actor and womanizer and finally a bespectacled murderer who has calculated that a hotel room is the perfect setting for the murder of his victim, a Chinese politician passing through. As luck would have it, the three men swap rooms. As a result, the call girl, who is actually expected by the actor, ends up with the murderer, the respected businesswoman expected by the manager goes to the womanizer and the businessman's real wife, who (unexpectedly) turns up to accompany her husband, suddenly finds herself in the same room as the call girl and the murderer. Events come thick and fast and the murderer, whose glasses have been broken in the confusion, is unable to carry out his murder.
