Brother and sister, Tom and Bobby, are orphans growing up rough, with
their dog Tag, in the Victorian East End of London. Helped by Dr
Barnardo, they have begun to make progress when Bobby is attacked in the
notorious Rookeries. Tom comes to the rescue but finds himself arrested,
in a cell, and then before the Beak. His trial is at the Old Bailey
where he is not allowed to speak in his defence. Then Tag comes to his
rescue!
