Not many spoilers here, the plot is laid out very early in the episode. One of the premier document experts in the world is in Honolulu, and he's going blind. He won't have a useful career left after that.
So he concocts a plot to not only produce bearer bonds, but to have the authorities bring authentic bearer bonds to him so he can replace them with forgeries of his own making, and right under the nose of the police!
There are two problems with this plan. He commits two murders so there are no witnesses against him, and he has McGarrett and 5-0 trying to solve the case. He makes one critical mistake, which of course Steve homes in on.
Fascinating episode.
