From the producers of The Usual Suspects and Eternal Sunshine of the Spotless Mind comes this topical thriller inspired by actual events involving a popular British teen drawn into a tense MI5 investigation after falling for a troubled Internet seductress. When 16-year-old Mark (Jamie Blackley) meets smoldering Rachel (Jaime Winstone) online, it's love at first chat. Before long, smitten Mark has even befriended Rachel's bullied younger brother John (Toby Regbo) -- a good kid trapped in a desperate situation. That situation becomes a matter of life or death when Rachel is brutally murdered by her abusive boyfriend. Meanwhile, as Mark and John prepare to seek revenge against Rachel's killer, they learn their actions may disrupt an important investigation by MI5. Later, Mark is coerced into committing a crime that shakes the British legal system to its very core.
