	Synopsis: 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...
