Country star Tim McGraw is joined by 'American Idol' judge Keith Urban and none other than Taylor Swift in his dramatic video for 'Highway Don't Care.'

Swift doesn't interact with any of her costars in the clip, only singing her parts while partially obscured behind a curtain. The video mostly focuses on the dangers of texting and driving, with a young crying girl -- the very kind to which Swift's music appeals -- driving dangerously with a cell phone. We won't give it away, but it's graphic, disturbing and heartbreaking ... and there's a twist.
