Samantha and Darrin are now in lovely Paree and Endora is home with Tabitha and Adam. Maurice comes by the house and finds out that the Stephens are vacationing in Europe. He is mad because they should have stopped by in London to see how he was doing. Endora flies to Paris to warn Samantha and then Maurice appears in a scary cloud of smoke. Out of rare kindness, Endora zaps up a fake Darrin who charms and pleases Maurice. Everything just seems all right until the real Darrin comes in. Maurice notices the trick and sends poor Darrin to the top of the Eiffel Tower. Unbeknownst to him, his very appearance there makes a perfect advertising campaign for one of his clients who runs a travel agency.
