A mysterious virus, nicknamed Medusa, is spreading around Japan, turning its victims into stone. Given the impossibility of finding an immediate cure, the government opts for cryopreserving a select group of patients until they come up with a solution. Kasumi, one of the chosen ones, has been asleep for years and her awakening, more than a bed of roses, is a bed of thorns, and happens in the midst of total chaos where monstrous creatures lie in wait all around. Based on Yuji Iwahara's manga by the same name, puts animated images to a sensational cross between Aliens and the series Lost. Enigmatic and highly explosive.
