[3] Spoilt children Henry and Caroline are excavating an ancient burial site when two crooks, having stolen a gold cup and hidden it in the site, return to retrieve it.

The film was inspired by the late 1930s archaeological discovery of Sutton Hoo.

[4] The film was made on location in Suffolk including scenes in Ipswich Museum, Rendlesham Forest and on the Deben River.

The plot is contrived and becomes somewhat confused through the introduction of incidents relatively unimportant to the main story-line – for instance, the overemphasis on the inconsiderate nature of Henry and Caroline, already established as spoilt children.

The chase sequence makes an exciting climax, compensating for some slow development in the early stages.
