Le père de Léo est malade. L'unique remède susceptible de le soulager, puis de le guérir, est de la glace. Mot se rend alors au pôle Nord afin d'en chercher.
Feverish, Leo's father is suffering from a major attack of flu. He tosses in his bed beneath the myopic gaze of Dr. Meurz who requests some ice for the poor man's fevered brow. Mot, with much good will and clad in a nurse's uniform leaves immediately for the North Pole. Upon arrival the Tellurian is frozen by a violent blizzard and so neglects to close the time doors. Ice floes and penguins spill into the house. The myopic doctor frantically auscultates a sea-lion. A Russian submarine moves about in the bedroom. Battling alone against this torrent of catastrophes, can Leo save his father from the jaws of a polar bear and defrost Mot whose head occupies the vegetable crisper in the family fridge?
