Appointment with Venus

In 1940, after the fall of France, the fictitious Channel Island of Armorel is occupied by a small garrison of German troops under the benign command of Hauptmann Weiss. The Ministry of Agriculture realise that during the evacuation of the island, Venus, a prize pedigree cow, has been left behind. They petition the War Office to do something urgently due to the value of the cow's bloodline, and Major Morland (David Niven) is assigned the task of rescuing Venus.
