Sergeant Hawk is dispatched to Japanese-occupied Manila to verify reports that the enemy plans to abandon the city as an undefended, open city. His mission takes him to a nightclub perched in the middle of a ship channel, the headquarters of a double agent hiding crucial unsent dispatches that reveal the Japanese intentions.

As Hawk scours the nightclub for the documents, he discovers a portrait of the beautiful female agent who concealed them along with her mysterious plan for him, devised before her untimely death. Hawk must now decide if following her directives will save his patrol from the imminent collapse of Manila or lead them to destruction.

Will Hawk unlock the secrets hidden within the nightclub and secure his patrol's safety, or will the city's fall spell their doom?
