Producer Tara Subkoff's ('The Killer Inside Me') directorial debut examines the harsh consequences of social media addiction taken to the extreme, reported Digital Spy.
Purportedly inspired by true events, a group of pre-teen girls face a night of sadistic thrills and sadism as revenge for taunting a classmate.
Subkoff has put together an impressive cast of adults as well - with Chloe Sevigny, "Orange Is the New Black" star Taryn Manning and Natasha Lyonne, Oscar winner Timothy Hutton and "Twin Peaks" star Balthazar Getty all in supporting roles.
"#Horror" releases on November 20 in US cinemas.
