Unleashed is back with a brand new series. We get to know the new companion, Varada Sethu, and we're at home with Russell T Davies. Steffan starts some explosions and meets some cool giant robots! There's a lot to see and even more to find out!

We go behind the scenes of this spine-tingling episode and hear why Rose Ayling-Ellis is having 'the best time ever!' Steffan lays camera tracks in a quarry, and we catch up with Ncuti on the beauty of acting using British Sign Language.
