If you only know of Megan Fox and Machine Gun Kelly‘s romantic saga, you may be surprised to learn Fox and Colson Baker (MGK’s real name) first met professionally on the set of Midnight in the Switchgrass. Because judging by the movie’s first trailer, which ET is exclusively debuting, the experience was intense.

In director Randall Emmett‘s thriller, FBI agents Lombardo (Fox) and Helter (Bruce Willis) team up with a Florida state cop (Emile Hirsch) to catch a serial killer (Lukas Haas) who abducts young girls from truck stops. “We’re supposed to be protecting these girls,” Fox’s Lombardo argues in the footage.

And so, she goes undercover, first in a hotel room sequence opposite Baker’s character — in which she promptly beats him to a pulp — and then a sting operation which goes horribly wrong, leaving Lombardo’s life hanging in the balance amid a twisted game of cat and mouse. “The minute I got made bait, it became my operation!” she argues with Willis’ Helter. Check out the brutal, bloody red-band trailer above.
