Colonel Jack O'Neill and his SG-1 team find themselves stranded on a primitive world where the inhabitants pay homage to the Goa'uld by providing their best specimens as host bodies for their young. Doing so, they would avert total annihilation...while the hosts would be doomed to a living death. For years, the helpless supplicants have been sacrificed. With the new "payment" about to be sent, the team struggles to rescue a terrified populace that does not want their help, while facing the possibility of being marooned forever. And one fact overshadows all else - the Goa'uld are already on their way...
