Having helped three men load things into a van at the palace Hubble is told that he has inadvertently assisted thieves in stealing valuable pictures from the Royal art collection and is charged with delivering the five million pounds the criminals demand for their return. Handcuffed to the brief case containing the money he is taken to a farm where he meets the mastermind behind the heist - Sir Ambrose Hamilton,the Surveyor of the Royal Pictures. This leads to a shoot-out in an ice cream van and another accidental triumph for Hubble,who literally remains cool throughout.
