Bobbie goes to the aid of Charles, a filmmaker, trapped in an ice hole by a wartime bomb. A pretty lady journalist (Ingrid Pitt) sees a scoop in the news. The journalist is covering the de-fusing of the bomb—but the local people don't want her to write about it. Bobbie is the only one who can possibly enter the hole and defuse the ticking gadget.
