Guardians (2009)

Twilight Cove, a small, overlooked town, is overrun by monstrous creatures that have appeared from another dimension. If they aren't stopped soon, these creatures will spread and threaten the entire world. As night falls, a battered truck arrives carrying a group of experienced mercenaries. This isn't their first assignment; they are part of a hidden society with a long history of protecting humanity from threats both earthly and otherworldly. Their mission: to safeguard our world from evil, both created by us and originating elsewhere.
