After his stakeout turns into a kidnapping, private eye Harry Brown (William Forsythe) enlists the help of a Five-0 to find a missing woman (Lena Georgas) whose husband believed was having an affair. After his refusal to pay, the man's mistress (Melanie Rains) is taken by masked men as well, leaving McGarrett (Alex O'Loughlin) and his team limited time to find both women. The case has a twist you'll likely see coming if you are paying attention, but the tension still works well-enough. The showdown with the kidnappers also shows off Kono's (Grace Park) sharpshooting skills.
The episode's B-story involves the unexpected appearance of Danny's (Scott Caan) ex-wife Rachel (Claire van der Boom) whose current marriage is dissolving. Danny's attempts to help, mostly off-camera, don't amount to much, although he is able to be their when the pair break the news to their children. The question for Dano, is what does this news mean for his relationship with Melissa (Lili Simmons)?
