S02:E07 - London Calling

The explorers discover a map revealing a way off the plateau and out of the Lost World. The group makes their preparations to leave, packing whatever evidence of their findings they can, but Veronica knows she must stay to continue her search for her parents. Despite Nelson's uncertainties about going back, they follow the route outlined in the ancient map and emerge on an ocean coast. While it appears that they have finally found their way back home, not all is what it seems.
