 While Janeway is visiting her da Vinci holodeck program, Voyager is mugged by transporter. They steal everything from the main computer core, to the emergency rations, even the dirty laundry! They track the property to a trade outpost. When they take a team to recover the gear, Janeway is shocked to find her holodeck character da Vinci (guest star John Rhys-Davies) - wearing The Doctor s mobile emitter living there. He believes it is America, and tells her he has been hired by the Prince as an inventor. With da Vinci s help, she gets the computer back, but the  Prince  and his men chase them into the hills, where da Vinci s newest invention awaits to help them fly away.
