A group of men working in the closed circuit surveillance of a large shopping centre are overwhelmed by a sense of danger and are becoming entrenched in hostility and suspicion. Their ability to work together is seriously impaired, and their health is at risk. The management decision to call in therapeutic support enables the group to emerge, via a detailed enquiry about their bodily and affective states, from the denial imposed by the management over the toxic aspects of their work. The arousal caused by witnessing violence, alternating with long periods of no action, is seen as a major cause of dangerous dysregulation and toxicity, together with the effects of being cut off, isolated, and exposed to the shaming, voyeuristic compensations offered by the work of watching while remaining unseen.
