Helen and Dale's new alliance has become the talk of the office as they cover the much-hyped return of Halley's Comet. The closer Dale draws to Helen, the more he finds himself thrust into the spotlight.

When news breaks of Lindy Chamberlain's imminent release from prison, Helen, Dale and cameraman Tim fly to Darwin. But they'll face fierce competition as they fight to land the "interview of the century".

Helen is deeply apprehensive about meeting Dale's mother, while Dale gets lumbered with Royal Wedding puff pieces. But their everyday concerns are thrown aside when a bomb goes off on Russell Street.

Dale's career and his relationship with Helen couldn't be going any better, until his prized interview with an HIV-positive mother goes horribly wrong. In the eye of a media storm, buried secrets come to light.

While Helen is still reeling after Dale's revelation, reports emerge of a nuclear accident in Chernobyl. In the face of great fear and uncertainty, the pair must confront who they really are to each other, and to themselves.
