Mimiki ke kai, ahuwale ka papa leho (When the Sea Draws Out the Tidal Wave, the Rocks Where the Cowries Hide Are Exposed)

Crime spikes when a heat wave hits Oahu, causing McGarrett and Danny to hunt down a bank thief, and Tani and Junior's car is stolen while they're on duty. Also, Grover plays the golf game of a lifetime, and Kamekona incites a riot by price-gouging on his shave ice.
