Fire Twister

When ex-firefighter Scott Nylander and a group of ecologists approach a silo filled with oil to hang a banner with an eco-message, they suddenly realize they came to the wrong place at the wrong time. There's a bomb attached which is going to explode in a few seconds. As the group finds shelter, a mass explosion causes a huge flaming tornado, which starts to destroy everything in its way. Scott and his team are accused of being terrorists that caused the explosion and must now stop the fire twister before it destroys LA.
