Whilst on holiday in Haiti, Sharron investigates a plot to brainwash important figures in the worlds of politics, science and business, apparently orchestrated by a local sorcerer, Damballa. Richard and Craig become involved later, only to discover that Sharron has apparently been discovered by the plotters and brainwashed herself.

Craig is captured after a mission in Hong Kong, and held in a cell where he is subject to interrogation by various cruel means. The unnamed interrogator (Colin Blakely) wants information about Craig's last mission. Despite nearing breaking point, Craig escapes the room, only to find he is at Nemesis headquarters; the interrogator is a member of Nemesis internal security, charged with finding out how Craig completed his last mission (his report had been less than clear at certain points, which were where his powers had come into play). Tremayne halts the investigation over the interrogator's protests, but the episode ends with Craig expressing bitterness towards his colleagues for their failure to intervene. All of the three are unhappy with Tremayne as well, owing to his part in the interrogation.
