Charlie Quick, known as 'Grandad', is the caretaker of the Parkview Rehearsal Hall. During the rehearsal of a television show he decides to help young Brian Plumber with his dancing career. The help gets out of hand and causes chaos!

Grandad's cooking causes worse than indigestion - it's capable of wiping out Mr Digby Rigby's entire cast! The only solution is a food dispenser in the Rehearsal Hall, so Grandad determines to get one.

Grandad's umbrella becomes the target of two notorious thieves. It contains a necklace worth £10,000.
