Holy Mountain


The true story behind the unmasking of Mark Kennedy, the undercover police officer who infiltrated environmental campaigning organisations over a period of seven years. During this time he had had a series of sexual relationships with women who were unaware of his real identity. After a legal action in 2015 Scotland Yard have issued an unprecedented apology and paid compensation to some of the women, but they have not said how or why they were targeted.

Steve Waters’ drama examines the events leading up to Kennedy’s unmasking by the activists with whom he had these intimate relationships.

Deep Swimmer depicts real events although names of the activists have been changed.
