Appleseed The Movie (2004)

The year is 2131. A non-nuclear war has left the earth barren. Deunan Knute roams the badlands, one of the many soldiers who, with lines of communication cut, continue to fight, unaware that the war has ended. Deunan is never one to take things lying down: a highly trained soldier with police and SWAT experience, she is prepared for nearly anything -- but not for the heavily armed helicopter that assaults her without warning. Before she realizes what's going on, Deunan is losing consciousness: her last thought is a hazy realization that she's been hit by a tranquilizer. Not only that, but one of the perpetrators is her old love Briareos. He has arrived with the beautiful Hitomi to intercept Deunan and take her back with them to the enigmatic utopia, Olympus.
