Frosty has returned from the North Pole but even the presence of the kids doesn't seem to ease his loneliness. The children decide what Frosty really needs is a wife so they build him one out of snow and Frosty names her Crystal. In all that attention Frosty is getting however, another wintery soul--Jack Frost--is becoming rather jealous. Jack decides that if children are ever going to love him as they do Frosty then the snowman and wife would have to go!
