On the verge of making it big, long-struggling musician Jack Frost (Keaton) realizes he's missing something vital: time with his wife (Kelly Preston) and young son Charlie (Joseph Cross). But before Jack can make up for lost time, he swerves off an icy mountain road. Then, one cold winter's night, Jack returns as a snowman! He embarks on a riotous, snowball-chucking, snowboard cruising quest to show Charlie that when it comes to being totally cool, there's no dad like a snowdad!
