Cleaner

A group of radical eco-activists takes 300 hostages at a luxurious party in a skyscraper to expose the corrupt top officials of an energy company. However, among the gang, there is a true madman whose plans involve killing the hostages as a manifesto of anarchy. Only a fragile girl, who happens to be on the other side of the windows of the impenetrable skyscraper - a former special forces soldier, now a simple window cleaner - can save the people from death.
