On a tip from Hoshi's telepathic admirer, Tarquin, Archer and the crew head to a nearby planet, hoping to learn more about the mysterious Xindi weapon. Archer, Reed and Major Hayes embark on a reconnaissance mission and discover that the sparsely-populated planet is home to an elaborate Xindi-Sloth manufacturing plant producing canisters of a substance called kemocite. The team manages to swipe one of the canisters, which is then transported onboard Enterprise for analysis. Unbeknownst to the Enterprise crew, Degra, one of the Xindi-Humanoids, is close to testing the weapon and needs only one more shipment of kemocite to do so.
