An enjoyable children's adventure. When Roger (Tony Wager) discovers that his Dad's Rembrandt has been stolen from the supposedly secure vault at his mansion, he begins to investigate with John (Ivor Bowyer) the butler's son. They find a secret tunnel that leads from the vault and suspicion falls on the cook Mrs Matthews (Thelma Rea) and the antique seller Mr Harvey (Frank Henderson)...
Then a gang is let into the house by Mrs Matthews to empty out the rest of the vault. The two boys are captured but manage to escape and then help the police find the gang's hide out...
A straight forward adventure with plenty for viewers (of all ages) to enjoy. The story is fairly cliched but there is nothing wrong with good old fashioned fun.
