Upon their arrival in London, the Stooges endeavor to secure employment with Scotland Yard subsequent to their completion of studies at a correspondence detective school.

Unbeknownst to them, the castle's staff are complicit in a scheme to pilfer its treasures, taking advantage of the Stooges' presence as they slumber within its walls.

However, the Stooges ultimately apprehend the perpetrators, led by the nefarious Lorna Doone, who, under the guise of the Earl's secretary, orchestrates the clandestine operation.

Their triumph is ephemeral as, amidst their jubilation, they encounter a bagpipe-playing skeletal apparition, prompting their hasty departure from the castle premises.
