First trailer for 'The Vow' arrives

This one won't hit theaters until next Valentine's Day, but a first trailer for Michael Sucsy's "The Vow" is already online. The drama stars Channing Tatum and Rachel McAdams, and judging by this footage, it will try to steal your heart. But will it succeed?

The story of "The Vow" follows a couple getting into a serious car accident. When the wife (McAdams) awakes from a coma, she doesn't remember her husband (Tatum), which prompts him to try and win her heart all over again. Yeah, that's a tough one for sure...
