Pukana is the 11th episode of Season 4 of the 2010 remake version of Hawaii Five-0.
Hawaii Five-0 are left stunned when a murder investigation turns up evidence suggesting that the person behind the crime may be a serial killer which puts one of the team in great danger. Meanwhile, Danny and Grace find a mysterious puzzle box washed up on the shores of Oahu.
Five-0 investigate the murder of a serial burglar, later identified as Victor Dobbs by Kamekona, at the trunk of a car. They find a laptop at his residence containing a list of all the homes Dobbs burgled. As Catherine and Chin search the houses, Five-0 receive a visit from the FBI, who informs them that the murderer is a serial killer who killed at least 14 women after imprisoning them for 24 hours. Chin finds the house where Dobbs was killed, only to be held captive by the owner, Gary Nathan, the serial killer, who later kidnaps his girlfriend when she makes an unexpected visit.
While Nathan is distracted, Chin manages to break himself free and kill him. Meanwhile, Danny and Grace find a puzzle box washed up on the beach, from Japan after the 2011 tsunami, with a locket and a girl's face in it. The girl is found to have died during the earthquake.
Danny and Grace then travel to a temporary housing shelter in Ishinomaki, Japan to return the box to the family's only survivor. Kono's trail to Adam leads her to Vancouver, British Columbia.
