Just as the ransom money has been delivered, the kidnap victim escapes; one of his two kidnappers falls to his death trying to chase him. The surviving kidnapper concocts another scheme: he holds the ransom money (which is hot) hostage and tries to coax the kidnapped boy's greedy father into laundering it for him. The kidnapper, an accomplished scuba diver (the source of the episode's title) plans to swim underwater to and from the dropoff point. Five-O identifies the kidnapper and tails him, at one point donning frog masks in an attempt to rub his nose in his activities, but the kidnapper relies on the father to shake any tails and deliver the money to him at 25 cents on the dollar, the standard rate for laundered money. It sounds like a great bargain for the father and he holds up his end of the deal -- but that's not the end of it. Written by Peter Harris

Generally good, but one part of the episode made little sense...
4 December 2009 | by MartinHaferSee all my reviews

This episode is named the way it was because a rich guy's young son is kidnapped and the kidnappers wear a frog and a devil mask so the child cannot identify them. The film begins with the kid in their custody, but the smart little nipper makes his escape. In the meantime, his father has already paid the ransom (doh!). So it's up to McGarrett to discover who the kidnappers were as well as find the money.

Fortunately, it wasn't hard to find the hideout and they also find one of the kidnappers...dead. It seems he fell and was badly hurt when he was chasing the kid in the darkness. So, his 'pal' shot him because it was too much trouble to try to save him. Nice guy, huh? McGarrett knows that the first thing the kidnapper will try to do is sell off the money to a rich crook who can hold it for a few years until the heat is down and it won't be recognized. So, McGarrett does his best to scare all the rich crooks on the island that could purchase this hot money--to scare them and force the kidnapper to try to spend it.

In a bizarre twist, late in the episode the rich guy is contacted by the kidnapper and he is offered his $300,000 back...for $75,000. This is because the crook just can't sell it. This makes no sense for two reasons. First, wouldn't this $75,000 be just as hard to spend?! Second, why wouldn't the rich guy tell McGarrett--and that way get his money back AND save the extra $75,000?! Duh. I really wish they'd worked all this out, as the show ended on a sour note. Otherwise, a good show--and I really, really wish I could get one of those Mr. Frog masks--it was so cool!
