The first trailer for Jennifer Lawrence's psychological thriller "mother!" is here, and it's equal parts confusing and creepy.

Lawrence and Javier Bardem play a couple whose relationship is tested when uninvited guests -- including Ed Harris and Michelle Pfeiffer -- begin trickling into their home. The Darren Aronofsky film centers around love, devotion and sacrifice -- and creepy music.

The trailer (above) provides very few answers to the questions provoked by the 30-second teaser Paramount Pictures released last week, but here's what we do know: Lawrence's character and Bardem's character are in a relationship. Lawrence spends a lot of time walking through her creaky home, very slowly, while looking terrified. Bardem may or may not be a "bad guy" and on the side of the strangers he keeps letting into their home. A photo of Bardem is left torn into pieces.

"mother!" hits theaters Sept. 15.
