Peter Vaughan (Fox) and Ewen Solon (Maigret) star in this six-part adventure series, written by Dr Who contributor Don Houghton and aimed at a teenage audience. The Doombolt Chase combines science fiction and naval intrigue, with location filming, authentic action scenes and a constantly surprising plot. Originally screened in 1978 and produced by HTV – the independent company known for several memorably successful children’s series, including Arthur of the Britons, Sky and King of the Castle – The Doombolt Chase is available here for the first time in any format and has been transferred from its original film elements specifically for this release.

When Commander David Wheeler is arrested for a seemingly motiveless attack on a mysterious vessel, his son Richard, along with friends Lucy and Peter, embark on a search for the secret information that might clear his name – becoming entangled in an intrigue of codes, espionage and a fearsome new weapon under the sea.
