The Inheritance

As Dennis's death becomes the subject of an official police investigation, with Detective Sergeant Morris leading the charge, the siblings hunt for their father's previous will, trying desperately to prove his original intentions.

Daniel finds himself in hot water with Sian's aggressive ex-husband Glen who, unbeknown to Sian, has given Daniel a loan to help with his struggling restaurant and is now demanding that Daniel help him to see his and Sian's son, despite a restraining order. Sian, in the meantime, is developing a crush on the estate agent who valued their father's house.

Susan is meddling in the siblings' lives – threatening to reveal Chloe's secret… (that she knew about the affair all along and didn't tell Sian or Daniel). The siblings discover that Dennis's oldest and best friend Michael was Susan's ex-husband, and it seems that Dennis was secretly sending Michael money – but why?

Daniel also finds bioethanol hidden in Michael's garage. So, believing that Michael is involved in his father's death along with Susan – and desperately trying to remedy his own financial mess - he goes to demand that Michael gives him back the money.

The Watsons' lives become more complex after a burglar targets the family home. Daniel gets increasingly desperate to pay back his loan as Glen becomes more threatening and demanding. Sian is now dating estate agent Nathan, resulting in a nasty run-in between the estate and a jealous Glen.

The body count starts rising as Sian finds a dead body at the family home. As the siblings discover more about what happened to their father, they hurtle towards a fiery conclusion.
