Zach promises to drop off his father’s film at the lab before going on a hike with Annie, but decides to do the hike first. When he and Annie get stranded on a steep trail, Sock goes for a rope while Ari tells a story to boast Zach’s courage. They get off the trail safely, but Zach doesn’t make it to the lab before it closes. Now he must have the courage to tell his father of his mistake.
Embarrassed that his history project -- a reproduction of a relic that his father brought back from a trip to Egypt -- is too lame, Zach tells his class that the relic is real. When his teacher asks permission to display the ancient relic in the History Fair, Zach’s “harmless” embellishment is in danger of becoming a major school-wide deception. Concerned that this would harm Zach’s integrity, Plato tells a wise and well-known tale about a boy whose lies get the better of him.
