Missing in action

Buck, Tumb, Sonny and Cindy have volunteered for a secret mission, and are practicing flying cargo planes across mountainous terrain.

They're soon off to Afghanistan with new identities.

Their cover: relief agency pilots. Their goal: locate a CIA agent who's gone missing while investigating an international arms ring.

Between the traffickers, the government-imposed guides and the corrupt civil servants, will they find anyone they can trust?
