Watch at FMovies. A serial killer played by Jake Gyllenhaal travels through the hippest parties on a killing spree of Dalston hipsters. Gyllenhaal masters the role of unsuspecting dark-eyed psycho as he pumps iron and gums drugs preparing for his next beautifully fashionable victim. Transforming a music video into magnificently dramatic cinema, director Daniel Wolfe has captured contemporary London in a shockingly addictive modern slasher.
