A terrified teenage girl with visible signs of physical abuse is brought into hospital by her “uncle”, but before the nurse treating her can alert Family Services the girl and the man disappear. So the nurse calls in the Five-0 instead, and Steve and Kono set to work. The girl is identified as Moani, missing for six weeks from her home, and lured into running away, then coerced into sex work, by someone she met online. It turns out that this isn’t an isolated case; there’s a sex trafficking ring on the island. Kono takes the case personally, and her righteous anger is something to behold, even if the guy whose car window Kono smashed in might reasonably think that all he was doing was sitting there minding his own business.
The trafficked girls are found by the end of the episode and taken to Pearl Haven, a specialised (and genuine) treatment facility, run by an organisation named Ho‘ōla Nā Pua. This might explain why the episode had an underlying hint of PSA, although not off-puttingly so; anyway, on any view it’s a worthy cause, and anything which can be done to educate young people and their parents is worthwhile.
There’s also a B-plot in which two recovering addicts are found murdered in their sober living home, together with their counsellor. Chin and Lou are on this one, although it’s no more than filler. And there are one or two references to something which happened with “Jack”, which confused me at first, but I’d forgotten about the MacGyver/H50 crossover episode. I’m not watching MacGyver, but I don’t think the crossover has been shown in the UK yet, so I might keep an eye out for it.
