Why are animals often most miserable when humans are happiest? Desmond Morris and Sarah Kennedy find out today as they explore the high life and the low life of the animals of London.
Desmond meets the Queen's horse. Burmese; visits the Pooches' Palace, where dogs are fed on steak and champagne; and discovers why one of Britain's most successful comedy writers, Carla Lane , enjoys living with a menagerie. And the prize-winning novelist,
Kingsley Amis, devotes his latest poem to Sarah - his cat. Meanwhile, at the other side of town, Sarah reports from the Battersea Dogs Home. More than two and a half million lost or unwanted dogs have been taken there since the home first opened in 1850. Today around 700 are waiting for a new life to begin. How many will find it?

The return of the five-part drama tracing the experiences of a group of disparate Australians in World War I. Starring
1: The Great Adventure August 1914. When the 'mother country' declares war on Germany, the call goes out across Australia for volunteers to fight for the Empire. It is answered by a group of men from different backgrounds, with different aspirations, for different reasons. In the 8th Battalion of the Australian Imperial
Force they find comradeship and laughter as they train for the battlefields of France.
But the laughter stops when Turkey enters the war and the battalion is thrust into the hell of Gallipoli and given a new identity: the Australian and New Zealand Army Corps -the ANZACS.
