Disaffected lab assistants Julie and Richard steal nerve gas from a research facility in Wiltshire and bring it to terminally ill Dr. Whittaker on Jersey. He threatens to release it unless he gets a million pounds from Sir Matthew Osterson, a former scientist whom he blames for his illness. Whittaker only wants what he considers his due but the young couple get greedy - and that helps Jim to catch them.
