After leading five people to Christ during their two ministry days in San Diego, the ""TruthQuest: California"" team packs up their bags and heads north to Yosemite National Park. The 8-hour bus ride takes an interesting turn when the Questers get lost inside the massive park. Along the way, the team decides to do something about the condition of the bus, Sarah beats the stuffing out of Chip, and Sparky hangs his head out of the window. Meanwhile, the normally quiet and reserved David undergoes a hilarious transformation. Eventually the team arrives at their destination and discover they will be sleeping under stars at elevation 7,000-plus feet. The following day the Questers meet North American Mission Board missionary Steve Hughes. Steve runs a recreation ministry inside the park and teaches the team how to hurtle down a 170-foot cliff. It's a challenge that leaves one of the Questers in tears.
