Five Australians on a sailing holiday come across a fishing boat full of desperate asylum seekers. Deciding to help, they tow the boat but, in the middle of the night, it disappears. Years later, one of the Australians, Ryan, steps into a taxi driven by one of the refugees, Ismail.

Ismail, grieving the loss of his daughter, reports the crime at sea to the Australian Federal police and the Australians are investigated. Secrets start to come to the surface and Ismail turns his suspicions closer to home.

The Australians are found to have no case to answer but cannot feel relieved, as they continue to struggle with all of the after-effects. Ismail seeks revenge, which backfires, and the truth comes out.

The truth leads to a life in danger, as Ismail - blinded by grief - tries to get retribution, leading to a final confrontation and the possibility of new beginnings.

The crisis brings Olivia and Damien back into the fold of the family, and they put their own hurts behind them to act as support.

Helen, feeling helpless, offers to represent Bilal in court - he reluctantly agrees.
