Summit Entertainment has released a trailer for director Chris Gorak’s alien invasion frightener The Darkest Hour. Set in Moscow, the film follows five young people as their holiday trip is ruined by invisible extraterrestrial beings of light that disintegrate human flesh upon contact—and you thought cloudy weather was a vacation killer.

The Darkest Hour is produced by Timur Bekmambetov and stars Olivia Thirlby (Dredd), Rachael Taylor (Transformers), Joel Kinnaman (Girl with the Dragon Tattoo), Max Minghella (The Social Network) and Emile Hirsch (Speed Racer). It arrives in theaters on Dec. 23.
