Five-0 investigates the murder of rancher Daniel Kalakua, who was dragged by horses across his field, having uncovered human skeletons on his property. The remains prove those of the previous owners, who were buried with a fortune in gold coins. McGarrett deduces this murdered rancher was celebrating extravagantly at the local bar having finally discovered gold to pay his debt. Quinn's former stepdaughter Olivia seeks help after her father doesn't come home for three days. Adam and Kamekona help find Quinn's ex-husband Jake, an addicted gambler, at another gambling location, where Quinn has him arrested for illegal gambling and threatens to revoke his custody of Olivia.
