Sarah Adams is given a drugged drink by a taxi driver and is certain she was raped. After months of Sara feeling disbelieved by the police, her case is dropped and the man is free to attack again.

In 2008, it becomes clear that a cab-driving serial rapist is operating in London. An appeal leads a nurse who treated Laila to contact the police, which results in Worboys' arrest. Dozens of other potential victims come forward, including Carrie, who realises that he must have drugged her too. Sarah and Laila approach renowned solicitor Harriet Wistrich and decide to sue the Metropolitan Police.
