in two beautiful women, until they realise they might be KGB spies; Eric meets up with his relatives in what is a very positive experience for him; capitalist Alan has an argument with a die-hard socialist in a store (who is also on the opposing Russian academic team); Sarah and Darlene decide to record the sights and sounds of Moscow; Simone goes to put flowers on a poet's grave and meets up with a charming Russian musician; Dr. Samuels believes that his hotel room is bugged, but ends up making a fool of himself; and Charlie has a brief romance with a schoolteacher.
