Xmas Marks the Spot

On the way back to the fire house on Christmas Eve, the Ghostbusters unknowingly stumble through a portal to the past and into 19th century Britain where they run into Ebenezer Scrooge and capture the three Ghosts of Christmas. The Ghostbusters return to the present and find Christmas destroyed and quickly realize what happened. Without the three Ghosts of Christmas, Scrooge never learned his lesson and destroyed Christmas. Now the Ghostbusters must make sure that Scrooge learns his lesson, while Egon plunges into the Ecto-Containment Unit to rescue the three spirits, and return them to the past to rehabilitate Scrooge before the portal to the past closes.
