Jamie Ackerman (Mircea Monroe) is one of the few survivors of the disaster. 20 years later, in order to deal with the legacy of their parents, Jamie and her boyfriend and brother returned to this island full of horrible memories. Some people hope to find a way to kill the parasite through her, while at the same time, the latest variant of the parasite is spreading rampantly, and the lives of the islanders are under greater threat...
