When Chloe discovers Mxyzptlk's secret, he kidnaps her and threatens to kill her unless Clark purposely makes his team lose the championship game.

Meanwhile, Lex threatens Mxyzptlk with deportation unless he uses his powers for Lex's benefit. With his powers lost, Mikhail surrenders to Lex, but Lex decides to take him to a secret lab, 33.1, where he hopes Mikhail will regain his ability.
