After four friends perform a heroic act as children and gain psychic powers in return, they reunite every winter in Maine to hunt, drink and celebrate the special bond they share. However, this year's reunion is ruined when a lost and disoriented hunter stumbles upon their camp mumbling about strange lights in the sky. Soon after, horrific creatures begin to emerge and a heavily armed government operative, led by the psychotic Colonel Curtis (Freeman), attempts to take over the area. Challenged to stop this alien force, the friends must confront an unparalleled horror while they take part in an all-out battle to rescue the fate of humanity.
