Hardly Romantic (2015)

Sam and Jess are throwing their friend, Katie, the 21st birthday party of a lifetime. But, when nobody shows up to the party, it seems the evening is doomed to be another typical girls night in. Everything changes when three beautiful young men knock on the door with booze and party favors. The already drunk girls get drunker still, and it isn't long before they've drank themselves unconscious. What follows is an unrelenting, tense, and psychological massacre worthy of Sade himself.
