The day of the official launch of the Sonya Rebecchi Foundation arrives, and Toadie Rebecchi plans to gather everyone at the lake and make a heartfelt speech about his late-wife, Sonya.

However, there’s an unexpected change of plans when maintenance work near the lake means the event has to be relocated to the local Community Centre.

But as the residents of Erinsborough gather at the Community Centre, they’re unaware someone has left canisters of poison gas in the air vents…

Meanwhile, policeman Mark Brennan receives an anonymous tip-off about the poison gas peril and races to the scene of the crime.

But it’s chaos at the Community Centre as the poison gas starts to take effect on Toadie’s guests, and people start to cough and collapse including Sheila Canning…

To Toadie’s horror, he realises there is no sign of his young daughter, Nell. Afraid she’s in danger inside the Community Centre, Toadie races back in to find her…

Elsewhere in Erinsborough, this time pregnant Elly Conway is unable to talk her way out of trouble when Finn Kelly confronts her over her baby lie… so she confesses, yes, Finn’s brother Shaun Watkins is the real father of her unborn child after a one-night stand!

But the question is, what will Finn do now he knows Elly’s secret? Will he tell her husband, Mark?
