When someone gets ahold of the Barons' Wonderful Doppelgänger Device, which allows them to transform into anyone, they use it to land Rose in jail by posing as her to cause a small explosion during the Pitchfork Fair. The dastardly villain then ambushes W.B. and abducts him onto a train bound for the other side of the country. With W.B. out of the way, the imposter replaces him until W.B. returns unexpectedly and exposes the plot. Unfortunately, the deadly duplicate is great at impersonation. To save his skin, W.B. must prove himself by W.B.ing harder than he's ever W.B.ed before.
