John Travolta turns on the grumpy gravitas as a bluff, blue-collar hero.

He’s a Texas lineman dedicated to keeping the electrical grid running and to making sure his grown-up niece (Kate Bosworth) doesn’t fall for a wrong ‘un.

But a big tempest is brewing and Bosworth has her heart set on Devon Sawa’s scrappy new recruit to Travolta’s crew.

Brace yourselves for a perfect storm of disaster movie clichés and soapy melodrama, although this action drama does claim to be based on actual events.

Showing from 24 June.
