British Sign Language magazine series. In this children's special we join the Kaos signing choir as they perform with celebrity drummer Rowland Rivron, and Radha Manjeshwar checks out a new invention that claims to visualise sound for the deaf. Also, a deaf man will be sentenced for abuse of children in his care. We follow this up by talking to the victim of another abuse case, and finding out more about a new educational DVD that the NSPCC and NDCS hope will help keep children safe.
