When 25-year-old Mia Hoffman changed her testimony as a state witness and allowed a cop-killer to go free, she was vilified. Left with undiagnosed PTSD, she suffers extreme anxiety and hallucinations so vivid that she’s no longer sure what’s real and what isn’t.

Rejected by her friends, harassed by the police, and dismissed by the medical profession, a determined Mia forces herself to attend a residential alternative therapy training, led by Franklin Spitz, a British celebrity therapist who specialises in resolving the causes of PTSD.

But something terrible has happened to his wife, and a traumatised Franklin is hallucinating too. Using increasingly provocative psychological techniques, he probes Mia for the hidden memories underlying her condition.

But the goals of therapist and client are widely divergent – Mia is searching for reality and Franklin is desperately trying to avoid it.
