Time Team: Special: While digging a huge site in the middle of London, archaeologists uncovered two extraordinary Roman cisterns. At the bottom of each lay the remains of a complex mechanism for drawing water out from these five metre-deep containers. Tony, Mick and the Time Team are joining up with engineers, technologists and historians in an attempt to reconstruct one of these unique machines - and, in the process, discover how they worked and what they were for. Gradually the oak and iron components are pieced together, but whether the machine will actually work when all the parts are assembled is anyone's guess. The road to eventual success turns out to be quite a rocky one and, as the deadline looms ever nearer, it's not just the ropes that end up getting frayed...
