Armed with a multitude of crazy inventions, and alongside his eccentric allies Colonel Dedshott, Mrs Flittersnoop and young apprentice Connie, Branestawm, the original mad professor, takes on scheming businessman Mr Bullimore and officious local councillor Harold Haggerstone, to try and stop their plans to bulldoze his workshop to make way for a giant munitions factory, right in the middle of town.

When Lady Pagwell dies, leaving a substantial sum to fund local inventing, it could mean the end of Professor Branestawm's money troubles. But scheming local councillor Harold Haggerstone will stop at nothing to thwart Branestawm and insists that Pagwell holds an inventing competition to decide who gets the money.
