The good far outweighs the bad in this one.

It's odd that this is the second episode in a row that dealt with Soviet spies and Cold War tensions but like the last one, it's pretty original. The show begins with a guy getting assassinated on the beach by a pretty but very cold lady (Maud Adams). Why is uncertain but the man was an officer in the submarine service. Because a US Navy serviceman was killed, McGarrett is once again activated and now Commander McGarrett teams up with a navy man (Geoffery Lewis) to investigate. Eventually, it turns out that the man was murdered simply because he knew another officer in the training program--and these spies didn't want him to be alive to identify the fake officer they've inserted into the program. Sounds like a lot of trouble? Well, to get a new guidance system, the enemy will stop at nothing--not even a crazy plan--to get the information.

For the most part this is a good episode mostly because it's pretty original. My only complaints are logical ones that SHOULD have been worked out better. First, the naval officer assisting McGarrett didn't seem the least bit concerned when the fake officer has dental work that would indicate he's a fake! He even says that McGarrett has 'no evidence' to support his theory that the man has been switched!! This makes no sense at all. What also didn't make sense was how these spies were able to suddenly brainwash the real officer to go back to his duty and have no idea he'd been held incommunicado for all this time! Huh?! These logical errors aside, it's actually one of the better shows of season 10, but surely the good plot idea needed a bit more work.
