Welcome to Chain-Gang All-Stars, the popular and highly controversial programme inside America's prison system. In packed arenas, watched by millions of live-stream viewers, prisoners compete as gladiators for the ultimate prize: their freedom.

Fan favourites Loretta Thurwar and Hamara 'Hurricane Staxxx' Stacker are teammates and lovers. Thurwar is nearing the end of her time on the circuit, free in just a few matches, a fact she carries as heavily as her lethal hammer.

As she prepares for her final encounters, as protestors gather at the gates, and as the programme's corporate owners stack the odds against her - will the price be simply too high?
