Background[]
At night, a team wearing green Martian masks on their faces tail a unmarked truck and knock it over with harpoons guns, and steal refined kryptonite, an element from a Luthorcorp project. After Clark finds the hideout of the rogue operation, they trap him in an blast furnace. In the final confrontation, Clark defeats them by using all of his abilities to gain the advantage.
