High school group, so some can drive. They have to make it to a clandestine location without being caught by (chaperones playing) authorities--or real authorities (no speeding, etc). Fake checkpoints. "Jail". Only one is given the location, he has to communicate it somehow (this was before everyone had a phone). At the end, prisoners are brought in and interrogated. Wrap with a devotional about the persecuted church, etc.
