Peter Curtis (Ian McShane) has just been released from prison after serving four years for manslaughter. His victim’s mysterious last words were “High Tide’s at 9.52” - and now Peter wants to find out why. Heading South in search of answers, he books into a hotel – and discovers the only other resident knows all about him. Then he picks up a hitch-hiker, Celia, who may be far from innocent. Other people, it seems, are interested in those enigmatic last words and are prepared to kill to solve the mystery before Peter. As Peter conducts his search in the tidal estuaries of West England, he finds that there are far greater dangers than treacherous currents to contend with…Part of ITV’s hugely popular Armchair Thriller series, High Tide was originally broadcast as a four part serial and has been released on DVD in the United States.
