The film, which competed at the 67th Berlin International Film Festival and opened in the U.K. in October, follows Scott Thomas as Janet — a politician who has just been appointed to a key position, and throws an intimate gathering in her London home to celebrate.
While her home fills with friends played by Clarkson, Murphy, Bruno Ganz, Emily Mortimer and Cherry Jones, Janet’s husband Bill (Timothy Spall) gets ready to spill an explosive secret of his own: he’s leaving Janet for another woman.
From there, things appear to quickly unravel with the sophisticated champagne soiree ending in mayhem. Watch it all go down in the trailer for the film above.
The Party opens in select U.S. theaters Feb. 16, 2018.
