The Jensen Code
1974 - United KingdomBroadcast in thirteen parts from February 1973, The Jensen Code is a gripping children's adventure drama written by Carey Harrison, son of renowned actor Rex Harrison. The series stands out not only for its compelling plot but also for its moody atmosphere and psychological depth, which set it apart from many of its contemporaries.
At the centre of the story is 16-year-old Terry Connor, portrayed with conviction by Dai Bradley (fresh from his acclaimed role in Kes), who is sent to an outdoor activity centre in the rugged surroundings of Derbyshire. What begins as a typical youth camp experience quickly veers into something far more sinister. Together with fellow camper Alex (Tony Wright), Terry stumbles upon a covert scheme to steal a top-secret formula known as the Jensen Code from a nearby Ministry of Defence facility.
The stakes are raised dramatically when the code’s creator is murdered, but not before passing the critical information to Terry. From here, the series takes a darker turn: Terry becomes a marked boy, unsure of whom he can trust. The sense of paranoia is amplified when he wakes in hospital to discover that his memory of the code has been completely wiped. Is this the result of trauma, or has something more deliberate occurred?
The Jensen Code impresses with its slow-burn suspense and psychological intrigue. Its themes of mistrust, identity, and manipulation give the story an unnerving complexity, while the bleak Derbyshire landscapes reinforce a sense of isolation and unease.
While some aspects now appear dated, especially the pacing and production values typical of early '70s television, the storytelling remains strong, and the central mystery is absorbing. The performances, particularly Bradley’s, are earnest and believable, grounding the fantastical elements in real human emotion.
The Jensen Code was typical of its time, offering younger audiences a story that didn't talk down to them but instead challenged them to keep up. For those who enjoy vintage British drama with a psychological edge, it remains a fascinating, if somewhat overlooked, gem of 1970s children's television.
