When Scout Lewis returns home after studying abroad, she's disturbed by the change in her best friend Hedwig. A drug-fuelled night ensues, in which Scout rails against Hedwig's new, dark life, and by the time morning dawns, both girls have vanished.

When Scout is discovered after two days missing, she is determined to find Hedwig but shocked to realise she is under investigation herself.

As the search for Hedwig continues, crumbling movie-star Andy Dolan surfaces as a strange and crucial player in her disappearance.
