Arrest Bulldog Drummond!

Dastardly Rolf Alferson (George Zucco) has killed scientist Richard Gannet who has invented an atomic disintegrator machine that can explode anything nearby.

Bulldog Drummond comes across Gannet's dying body and is accused of his murder.

Now Bulldog Drummond has to clear his name while Rolf and his associate Lady Beryl plan to sell the weapon to the highest bidder. Even attempting to demonstrate the weapon on Drummond at one point.

As Bulldog Drummond sends Phyllis away for her safety. She ends up on the same ship as the Rolf and Lady Beryl. They see her wave goodbye to Drummond and places herself at risk.

It is unpretentious fun, with dastardly foreign powers wanting to buy the weapon. Bulldog Drummond, Algy and Tenny trying to evade the police. The script is a bit ropey in places.
