Heroes Unmasked - Series 1 - Head to Head

Behind the scenes of the drama series. We hear from the cast and crew as two of our heroes go head-to-head for the first time. With Nikki unable to stop Jessica taking on the role as hit woman and Parkman taking on a new job as a bodyguard, their ensuing battle sees Parkman come closer to death than any of our previous heroes. So how did Parkman get thrown out of that ten-storey window? And how did he appear to lie on the brink of death? Was it all down to 'green-screen' and a head for heights?
