BARK and HOWL are two puppies, born on the London underground
SHEBA is an elderly one-eared cat
When the Blitz begins, how will they survive?
It's the start of the Second World War and Bark and Howl are lost in the dark maze of tunnels under London.
With Sheba's help, they learn how to survive. But when the bombs begin to fall, the puppies become separated.
As the attacks continue, Bark and Howl are frightened, but they know the tunnels so well - they're the only ones who can lead hundreds of trapped people out of danger. Will Bark and Howl find each other - and be victorious in leading Londoners to safety?
