On the island of Mindanao, a man calling himself "General" Fertig has set himself up as a guerilla leader to harass the Japanese. Army records show that the only officer named Fertig in the Philippines is a reserve lieutenant colonel of the Corps of Englineers, reported MIA on Luzon, but sill, the reports filtering out are interesting, and it's Marine lieutenant Ken McCoy's mission to sneak behind the lines and find out if he's for real. With him is a motley group put together as a compromise between the warring factions of Douglas MacArthur and OSS chief Bill Donovan: verteran Marine gunnery sergeant Ernest Zimmerman; OSS captain R. B. Macklin, a bully who has managed to fail ever upward; submariner Navy Lieutenant Chambers D. Lewis; and Marine staff sergeant Stephen Koffler.

Together, these men will steal into the heart of enemy territory and there, amid firefights and jungle camps, encounter more than they bargained for. Before they're done, each will undergo a test of his own personal mettle – with results that will surprise even the most hardened of them.
