When Ponds Freeze Over -- Film Description:
"A mother tells her child a bedtime story of skating when she was a girl. Her father, skating with her, falls through the ice and the child jumps in after him. As the frozen world begins to close over her, she enters a dreamworld of animated memories and family stories. In trying to save her father, it is her memories that inevitably save her."
