At the end of one stop, French mercenaries led by Major Foster were ordered to protect an archaeological expedition led by Manio in Arabia. However, the main work carried out by the archaeological team is to dig graves and steal precious Arab cultural relics. Foster objected, but as a soldier, he must obey orders. The archaeological team's grave digging aroused the anger of Thrall, a powerful Arab leader who wanted to use the grave to awaken religious fanaticism among members of his tribe and then launched a fierce attack on foreigners. Beat the foreign invaders out of the country.
