High Treason

The film is set in Britain. A plan of sabotage is being prepared in the country. The targets are power stations. Those behind it want to bring the economy to a halt. The first incidents break out around London. Commander Brennan is put in charge of the investigation. Officers from the security service work with him. The team gathers information piece by piece. There is surveillance and there is listening. The file slowly grows thicker. In the end the threads come together. It is mostly ordinary police officers who crack it. Liam Redmond and André Morell take the leads, with Anthony Bushell also in the cast, in Roy Boulting’s British film of 1951.
