S.T.A.L.K.E.R.

A close-up shows a character's wide eyes and open mouth in shock, followed by a wider shot of two characters in a dark forest, one with blonde hair and the other with dark hair and glasses, both reacting in fear as they are thrown backward. The scene cuts to a close-up of a character's smiling lips, then to a dark forest where glowing lights float among the trees and a white, serpentine creature moves through the air.
