When psychiatric registrar Dr James Ford finds himself torn between a new mother attending a routine postnatal check-up and the sectioning of a floridly psychotic woman during a busy on-call shift, no one could predict the terrible consequences.

When another incident occurs in the unit, James clashes with colleagues and the hospital Trust.

In the wake of Maria Carter's evidence, the MIU's investigation turns a spotlight on Dr Hernandez and the obstetric department; when the Trust question their investigation, the MIU suspect wider cultural issues at the hospital.

The MIU refuse to concede to pressure from the Trust, looking closer into previous complaints that might shed light on the truth, but just how far will the Trust go to protect themselves?

With more questions than answers, the MIU are running out of time to piece together the truth; Dr Ford and the MIU discover witnesses unwilling to speak on record and hints of a wider conspiracy that leads far beyond the failing psychiatric unit.
