The Beach House (horror film: trailer).

Son of a beach! The Beach House is a horror movie set in the USA with an alien pod-people twist, where you’ll be dying to have a nice weekend by the sea.

Here’s the official blurb:

Escaping to his family’s beach house to reconnect, Emily and Randall find their off-season trip interrupted by Mitch and Jane Turner, an older couple acquainted with Randall’s estranged father. Unexpected bonds form as the couples let loose and enjoy the isolation, but it all takes an ominous turn as increasingly strange environmental phenomena begin to warp their peaceful evening. As the effects of an infection become evident, Emily struggles to make sense of the contagion before it’s too late.
