Ethan (Ethan Randall) and Hallie O'Fallon (Thora Birch) are two siblings who wish that their divorced mom, Catherine (Harley Jane Kozak) would reunite with their dad, Michael (Jamey Sheridan). As Christmas approaches, the kids manage to lock their mother's fiancé, Tony (Kevin Nealon), in an ice cream truck and have him whisked off to New Jersey, all in an attempt to make their mom believe that she's been stood up. The ploy works, and ex-husband Michael is waiting in the wings. Wikipedia
