Rottweilers, security guards and Victorian rooftops. Is this our maddest episode yet? [MANC PART 3]

This is it. The third and final installment of what has to be one of the greatest urban adventures ever. We've already overcome our fair share of obstacles and even showstoppers up till now, but none of that will compare to what's in store for us in the final stages of the mission. Two canal crossings and an incredible 200 year old rooftop ensure that this episode is just as hilarious and fascinatingly urban as the previous two, but an intimidating chain of office buildings and construction sites complete with rottweiler wielding security guards might just prove a step too far. Can we overcome all of this and bag ourselves another successful no roads mission? watch till the end to find out... ***good subtitles available***
