Charlie Chan in Honolulu

A murder mystery about a ship bound for San Francisco that takes a murderous detour to Hawaii. As the incomparable investigator awaits the birth of his number-one grandchild, his own scheming sons try to fill their father's shoes by solving a high-seas murder mystery on their own. But when a second victim is found strangled, it's up to Chan to tie up the boat-- and eventually the murder case.
