In 2010, indie rockers The National are about to embark on their biggest international tour yet when lead singer Matt Berninger invites his younger at times floundering brother Tom along to be part of the tour crew. Tom agrees, and brings his camera with him to document the journey. What follows is anything but smooth sailing. From Tom's highs to lows, the ensuing film "Mistaken For Strangers" is a entertaining meditation on success, failure, redemption, and brotherly love.
