Four great friends — Shiel, Greer, Abbie and Sam are on holiday and playing football in a school playground. One of them whacks the ball through a broken window below the gym hall. As the youngsters enter the basement, they are astonished to find themselves entering another life; moving into a world they could never ever have imagined. They are followed by Zebra, the mischievous black cat with two wiggly, white stripes on her back.
Who could have guessed they would soon all be magically taken back in time to the life changing events of World War II?
