The fifth and final season of Netflix's treasure-hunting drama concluded with cyclical narrative callbacks to earlier instalments, including a hurricane framing device and a wedding recreation. The narrative incorporated supernatural elements as various characters pursued a legendary artefact believed capable of reviving deceased loved ones, whilst the central couple formalised their relationship and welcomed a child honouring their fallen companion.

The resolution centred on the ensemble recovering a historical shipment of gold from the ocean floor, which they invested into reconstructing their community with the stated goal of enabling peaceful coexistence between historically antagonistic social groups. Individual character trajectories reached formal conclusions, with the female lead pursuing lethal vengeance against her friend's murderer before ultimately achieving resolution within the rebuilt society.
