SAMMY is a football crazy rescue puppy. MOUSER is a fearless grey tabby. Together they make an unlikely pair that won’t be parted, not even by the First World War.  As the war rages in Europe, Londoners are sending brave animals to help the soldiers – and Mouser and Sammy are soon on their way to the trenches. Boldly criss-crossing no-man’s land they make new friends, but will this be enough to help them get home again.
