Lightfoot entrusts Big Sky with their most important brief so far: to find a missing plane that was carrying one of Lightfoot's agents, Joy. She was on her way to give Lightfoot some highly valuable, but unspecified photographic evidence. Lightfoot considers the mission too important to entrust to Jimbo, and he is banished to a milk run.

Given the sinister nature of events uncovered involving an armed militia, a Pentagon connection, and the suspicious circumstances of Ian's death, Lightfoot asks Chris if he is willing to continue. Their own lives could be at stake now. Chris gives his pilots time to consider their decision, and all agree to carry on.
