A new Home and Away promo shows dramatic scenes as fraudster Bronte kidnaps Dana after she gets close to exposing her secret.

Bronte (Stefanie Caccamo) arrived in Summer Bay last month after meeting Irene (Lynne McGranger) at a hospital in the city, where Irene was having her annual health check.

When Irene introduced her to Harper (Jessica Redmayne), Bronte explained that Irene had approached her after seeing she was upset, and that she had poured her heart out to her.

Irene later explained to Harper that Bronte was very sick, and was undergoing tests for an autoimmune disorder.

However, before long we discovered that Bronte wasn’t sick at all, as we saw her on the phone to an associate telling them that Irene owns her own home and business, and that she’s a pushover.

In the weeks that followed, Bronte explained that her last remaining option was an experimental treatment in Canada, with a price tag of roughly $100,000.

Irene then made it her duty to raise the funds, and as more and more of Summer Bay’s residents fell under Bronte’s spell, Xander (Luke Van Os) helped her set up a crowdfunding campaign.

The money began rolling in, with Salt making a substantial donation, and many across the bay more than happy to help.

Then, when the Diner was shut due to a contamination incident, and Irene let slip that one of the affected customers was suing them for $50,000, Bronte conveniently mentioned that she too had been affected by the poisoning.

Her apparent exposure to the benzine – which had leached into the diner’s water system – had supposedly sped up the progress of her mystery autoimmune condition, leaving Irene wracked with guilt.

When the diner’s insurers announced that they wouldn’t be covering the claims, as Irene and Leah (Ada Nicodemou) had failed to adequately service the pipework, Irene decided that she’d fund Bronte’s compensation herself, and began working out how to raise $50,000.

The only person who doubts Bronte is Dana (Ally Harris), who quickly spotted the holes in the fraudster’s story. Yet despite her best efforts, she’s been pushed aside by Irene, and even boyfriend Xander and sister Harper have been unwilling to entertain her theories.

An earlier promo from mid-June first revealed that Dana would find herself held captive by Bronte and her associate as she came closer to exposing Bronte’s secret.

Now, a new promo, which aired after the latest Australian episode, gave us a more in-depth look at the action, as Xander (Luke Van Os) fears his girlfriend has gone missing.
