Stephen's initial suicide theory is upgraded to a homicide investigation as motives and suspects surface; mysterious signs start to haunt Ariki, who struggles to interpret what they mean, both for him and for the case.

Ariki suspects that Stephen's wheelchair-bound wife, Lois, is somehow involved in the case; when Ariki gets an alarming visitation, he goes on a bender; frustrated with the lack of progress, the locals deal out some vigilante justice of their own.

The homicide investigation ramps up; Stephen's wife, Lois, is brought in for official questioning; Ariki's inappropriate behaviour jeopardises both his professional career and the case; stood down from work, he finds himself lost in the wilderness.

Ariki's heroics are rewarded when he's reinstated at work; the Ryders celebrate a hundred years on the farm but the festivities are cut short when the guest of honour goes missing; a confession provides much-needed closure for the town.

A startling revelation at One Lane Bridge puts Ariki in a compromised position; Ariki's gift helps him solve the final piece of the puzzle; the ongoing tension between Ariki and Stephen builds to a deadly climax.

Two months later, Ariki is plagued by premonitions, and Stephen is depressed about work troubles. But a new case draws him and Ariki back to One Lane Bridge.

Charlotte and Haggis McCrae become the chief suspects. Blaming his visions for letting him down, Ariki fails to take heed when he's warned of another disaster.

After a date rape drug is found in Rosa’s system, suspicion shifts to Rob Ryder. Ariki gets too close to the prime suspects and jeopardizes the case.

Ariki is thrown off guard when a long-held secret about Joe comes to the surface, and a confrontation with Stephen changes their power dynamic forever.

Ariki makes an arrest, only to discover a new clue and a betrayal. At One Lane Bridge, he relives the events that led to Joe’s death and makes a fateful choice.
