Episode cast overview:
Erich Anderson ...
Commander MacDuff
Erick Weiss ...


The Enterprise is heading for the Epsilon solar system. A suddenly approaching alien ship uses scanners so strong that all crew members including Data lose most of their personal memories, even names and ranks, yet retain their operational and language skills. The external communications are down and computer data banks have been selectively wiped. Some, including the ship's manifest, are altered, so as to make a Commander MacDuff Executive Officer (rather then Riker) and the Enterprise is on a crucial mission in a war the Federation would be conducting for years against the Lysian race. The alien ship has been destroyed, they assume by the Enterprise, although there's no battle damage. While crew members behave differently, failing their normal reference patterns, MacDuff volunteers for a memory therapy Dr. Crusher suggests, so he can pretend for it to fail and press on the attack on the Lysian headquarters, but the war logic doesn't quite add up...

["Mac Duff" has been revealed as a Satarran bent on annihilating the Lysians]
Commander William T. Riker: With all the power that MacDuff had, to alter our brain chemistry and manipulate the computers, it's hard to believe he needed the Enterprise.
Captain Jean-Luc Picard: The Satarran weapons technology was no more advanced than the Lysian. One photon torpedo would have ended their war.
Commander William T. Riker: It almost did.

Meh episode - too many plot holes
26 March 2014 | by (Houston, Texas) – See all my reviews

As others have noted this episode is a veritable swiss cheese of ridiculous plot holes, and I won't go into them.

I just saw a rerun of this episode last night and was struck by how poor the performance of "Commander MacDuff" was. His delivery was awkward and unnatural, as if he had just learned them minutes before -- without a chance to really internalized them -- and was simply reciting them by rote. His speech to Worf, in particular, had an awkward cadence without any natural flow.

I can't recall seeing this actor in anything else, so I can't tell if he was just having a bad week when filming this episode, or if that's just how he is.
