Caught in the Machine follows the work of the UK's largest children's Intensive Care Unit. The unit takes children from all over the country and is often the last resort for those who can't be helped anywhere else.
What if it were possible to turn back time? Could it be that we have the power to think ourselves young again? That's the extraordinary claim of an experiment first conducted 30 years ago and recently restaged with six of the UK's best loved celebrities.
In episode two, each of the celebrity volunteers must come face to face with the lives they led in their heyday and take back control of their lives. For Dickie a trip to Lord's cricket ground brings the man he used to be back to life while Liz takes up painting again.
In episode three, each of the celebrity volunteers must come face to face with the lives they led in their heyday and take back control of their lives. For Lionel, the most resistant to the experiment, a trip to the London Palladium ends in tears, Kenneth is reacquainted with his beloved dogs while Liz has a read through of one of her old sit com scripts.
In episode four, it's the final day of the experiment and the last chance for the volunteers to achieve their goals. In one final goodbye to 1975, a dinner party will be a chance to test how far each of them has come and to see whether they really have turned back time.
This final episode explores the science behind the series and puts the idea that we have control over how we age to the test. Using members of the public, watch as Britain is put under the microscope to see how our environment, our preconceptions about old people, and how we behave ourselves can have enormous impact on how we feel about the elderly and how we age.
