Money Spiders - S4.E9

Two baddies (Zephyr and Wymark) create some ‘spiders' that route around networks looking for juicy bits of information that they can use to black mail people in a ‘get rich quick' scheme using something called Catflap. The Bugs team are called in when a man has this happen to him, and they set up a trap to lure the people responsible to them. However, this goes horribly wrong and Zephyr and Wymark end up with what they think is Catflap (actually it is just a fake.) So, they turn to Adam Mosby for help and blackmail him by saying that they will kill Alex if he doesn't get Catflap from The Hive for them. He agrees and gives it to them in the second part. Ros and Ed go to investigate about Zephyr and Wymark, but are caught and forced to make a run for it, to the top of the building. Luckily Ed has some equipment with him and they absailing down the side of the building. But, Ros gets stuck half way down, as she is panicky about getting caught (her glove got caught in the figure of eight)
