In this film, an on-call psychiatrist is assessing a young man who has been referred urgently by his GP. The psychiatrist takes a history in which she elicits persecutory delusions, third person auditory hallucinations, running commentary, thought insertion, and somatic hallucinations. She then makes a risk assessment, takes a drug history and assesses risk.

The patient is clearly suffering from a psychotic disorder and the most likely diagnosis is schizophrenia. Differential diagnoses would include a drug-induced psychosis.
