Second act twist: Corporate scum have taken the device intended to stop tornadoes and made it into a tornado creator, with which they've inadvertently unleashed the biggest tornado ever.
Final act climax: The device's control board has been shattered, leaving only an exposed floor panel with a grid-work of multicoloured electrical connectors in red, blue, green and yellow, and the tough guys have to short-circuit it by bridging the connections with their own bodies, while the science geek calls out where they need to place their hands and feet. If one of them falls across the wrong connections, it's game over.
