Annihilation

Lena, a biology professor and army veteran, lost her husband Kane after he is deployed on a special forces mission. She believes Kane accepted a suicide mission because she cheated on him.

Kane suddenly reappears at home, then starts convulsing. Lena calls an ambulance but government forces divert it to a secret facility. A psychologist named Dr. Ventress tells her a mysterious zone called the "Shimmer" has been expanding from a fallen meteor for three years. Kane's team explored the Shimmer, but only he returned, and he is now comatose. She wants Lena to join a new expedition to the lighthouse where the meteor landed. Lena joins to find answers for Kane's coma. Ventress also recruits the physicist Josie Radek, the geomorphologist Cassie "Cass" Sheppard, and the paramedic Anya Thorensen.
