In special upcoming episodes of Home And Away, a body will be unearthed, sending shockwaves through the town.
For policeman Colby (Tim Franklin), it's the phone call he never wanted to receive, but has been expecting for months.
Earlier in the year, Colby saved his young sister Bella (Courtney Miller) and his then-fiancée Chelsea (Ashleigh Brewer) from the clutches of his evil stepfather Ross (Justin Rosniak).
Colby's dogged attempts to stop the reign of terror over his family ended up in a deadly car chase with Dean (Patrick O'Connor) by his side.
Once they had Ross in their sights, Colby's rage took over and, in the heat of the moment, he shot and killed him.
The former River Boys quietly buried Ross and, along with Bella, swore never to speak of it again. Unfortunately, secrets never stay buried for long…
During a reunion night with former River Boys crew member Amber (Maddy Jevic), Colby is informed by his sergeant that Ross' body has been found.
"It's the phone call he's been dreading, but he's quick to cover his guilt with concern for Bella. But underneath, his mind has gone into overdrive," Tim, 29, tells TV WEEK.
He cuts the night short and races to find Dean, Bella and Willow (Sarah Roberts). As the foursome try to decide what to do next, Bella begins to panic and urges everyone to leave town.

Colby knows this will only draw suspicion and promises to monitor the situation at the police station.
"Colby isn't new to the inner workings of a murder case and knows running would solidify their guilt," Tim explains. "The closer he is to the case, the more likely he is to stay one step ahead of it.
As days pass, fear mounts among the group. Dean and Colby fracture as the investigation begins, while Ziggy (Sophie Dillman) can sense her boyfriend is hiding something.
Bella grows increasingly unsteady as the pressure mounts. But if she cracks, her brother will go to jail. Is this the beginning of the end for Colby?
