Home and Away is set to plunge Summer Bay into a storm of secrets, deception, and danger this week, as Lacey Miller makes a chilling decision that could destroy everything she holds dear.

What begins as a desperate search for truth soon spirals into a dark and dangerous game — one that could place her entire family in grave peril. The haunting memory of their mother’s fatal car crash

has long haunted Lacey and her brother Joel Langum. For years, the siblings have lived with unanswered questions and buried grief, but now, their father — police officer David Langum —

has reopened the investigation, determined to finally uncover what really happened that tragic night. His renewed pursuit of justice, however, ignites a firestorm of tension and obsession that threatens to consume the entire family.

When David sets his sights on Craig Wendell, a respected local counselor and the owner of the car involved in the deadly crash, it quickly becomes clear that there’s more to this man than meets the eye. Craig’s calm demeanor and charitable image hide a darkness that David can’t ignore. But when his official inquiry hits roadblocks — and the higher-ups warn him to back off — Lacey decides she can no longer stand by and watch.

Fueled by grief and a burning need for answers, Lacey takes matters into her own hands — and in doing so, crosses a line from which there may be no return.

In upcoming scenes airing this week, Lacey manipulates her brother Joel into helping her deceive their father. Together, they concoct a dangerous ruse, claiming Joel is having a panic attack just to lure David out of the office. Once he’s gone, Lacey seizes her chance. In a tense and suspense-filled sequence, she sneaks into David’s office, charming an unsuspecting constable to gain entry. With adrenaline pumping, she snaps photos of all her father’s confidential notes — evidence that could expose a deadly truth or put her directly in harm’s way.

But while Lacey believes she’s one step closer to uncovering the truth, the repercussions of her actions are already closing in.

When David returns home and realizes Lacey has disobeyed him, his anger is palpable. He’d made it clear she was to stay put with Joel, and her absence raises alarm bells. Back at the station, his fears are realized when he’s confronted by a warning from Craig Wendell’s lawyer, who threatens legal action if David doesn’t immediately drop the investigation. To make matters worse, David’s superior berates him, forcing him to face the grim reality that his personal quest for justice could destroy his career.

Emotionally unravelled, David confides in Justin Morgan, his frustrations and pain boiling to the surface. The weight of his guilt and fear for his children begins to take a toll — but unknown to him, Lacey’s already taken her obsession several steps further.

By week’s end, Theo Poulos is stunned to discover that Lacey has gone to terrifying lengths in her pursuit of the truth. She spent the entire night lurking outside Craig Wendell’s house, watching, waiting, and plotting. When Theo confronts her, she refuses to back down, revealing a new plan: she intends to contact Wendell directly under a fake identity. Despite Theo’s desperate pleas for her to stop, Lacey’s determination only hardens.

“You don’t get it,” she snaps. “He’s hiding something — and I’m going to find out what.”

But her confidence is masking growing recklessness. Later, Lacey lies to Theo, claiming she’s hit a dead end in reaching Wendell. In reality, she’s gone further than anyone could imagine — making a menacing blackmail call to the counselor himself. Her voice cold, her threat unmistakable.

Lacey’s once noble quest for justice has morphed into something darker — a dangerous obsession that could have deadly consequences.

This week’s Home and Away doesn’t just explore the mystery behind the crash — it peels back the layers of grief, guilt, and desperation that push a family to its breaking point. Lacey’s decision to defy her father’s authority and manipulate those around her reveals just how deep her trauma runs. Viewers will see a young woman unraveling before their eyes, blinded by the need to reclaim control over a tragedy that shattered her life.

But Craig Wendell is no ordinary adversary. Beneath his polished image lies a man with powerful connections and a ruthless instinct for self-preservation. Lacey’s attempts to expose him may make her his next target — and in a town where secrets have already cost lives, one wrong move could prove fatal.

As the tension builds, fans are left to wonder — how far will Lacey go for the truth? And when the line between justice and vengeance blurs, who will pay the price?

One thing is certain: the idyllic calm of Summer Bay is about to be shattered once again. Lacey has lit a fuse that can’t be undone — and when the explosion comes, no one will escape unscathed.
