Vietnam. 1969. Sgt. Joe G. is on a recon mission in Cambodian looking for the 9th Viet Cong Battalion's radio jamming support group. Meanwhile, slacker PFC C.J. Parker of the 4th Infantry Division is taking part in the US invasion of Cambodia. Parker is lured away from his unit by Eurasian prostitute Martha. Unbeknownst to Martha, her hooch (shack) has been booby trapped by the Viet Cong--so when she entices Parker inside he steps on a Bouncing Betty landmine that will only explode if he steps off.
