The moment Helen Steel confronts the former police spy who deceived her, before disappearing without a trace, is caught on camera at Sydney airport. The British social justice campaigner had flown from London to Australia to confront John Dines, finally seeing him face-to-face for the first time in 24 years. Dines, who tricked her into having a two-year relationship while he was working undercover, is now involved in directing police training courses in Australia. Steel is concerned about what he may be teaching.
