The sequel to the 2013 film 'Escape Plan' follows the further adventures of Ray Breslin, the contractor whose job it is to test the escapability of maximum security prisons. This time, Breslin and his team enter Hades, said to be the world's most elaborate prison, when their friend Shu Ren is kidnapped and held there. Hades is fully automated and capable of changing shape, making it Breslin's greatest challenge so far.
