Time is Money S01E04 - Episode 4

Sara Davies hosts the quiz in which contestants are given their prize money before they have answered a question, and must race against time to keep hold of it. Each player stands before an hourglass-shaped money timer that begins to drain as the questions are asked - and the only way of stopping it is to answer correctly. Once the money is gone, the contestant is out - and only one can make the final to play for the amount they have managed to save.
