Over eight compelling episodes, the stories of people who have been catfished, gaslit and deceived are told through first-person survivor testimony. In each episode, Red Flag explores the experiences of those who have been targeted by digital manipulators who use dating sites, instant messaging and fake personas to prey on and exploit their partners.

Viewers are introduced to a new lexicon of manipulative relationship terms - 'breadcrumbing', 'mirroring' and 'love bombing'. These are weapons available to those perpetrators who are all too ready to manipulate and abuse the individuals they come across.
