Bad luck follows a foreign exchange student named Mikail Mxyzptlk to Smallville; Clark takes the Crows to the State Championship Game; Chloe begins to forgive Clark; Lana becomes more upset; Lex's downward spiral continues.

What's up with Chloe: Chloe decides to do a story on betting, so she takes $80 to a bookie named Mikail Mxyzptlk during a Crows football game. Chloe tells him to put it on Smallville, but he tells her he has a bad feeling about them. She says she never bets against Clark Kent and walks away. As the game winds down, Mxyzptlk tries to sabotage the game by using his ability to jinx people. He says trip, Clark trips, but scores anyway. Chloe's up $80!

What's up with Clark: When Clark tripped, for the first time in his life, he broke a linebackers collar bone. Jonathan thinks Clark should give up football, he's hurting people. Clark can't do it and says that he tripped because he didn't have control of his legs. Martha tells him to find out what happened if he wants to play again.

What's up with Lana: Jason tells Lana he thinks Clark may be on steroids. She tells him not to worry, but he says he lied and told the coach Clark's test came back clean, even thou he never tested Clark. He didn't want him to tell anyone about their relationship.

What's up with Lex: Lex wonders why his father awarded a scholarship to Mxyzptlk, who's from the Balkans. His grades and test scores are average. Mxyzptlk tells him his potential is more than grades and makes a bet with Lex. If Smallville looses the state championship, then Mxyzptlk stays in America... If they win... well, he's positive they won't.

What's up with Mxyzptlk: First he tries to get Chloe to can her article about him, she of course refuses. So he shows her his power by making her kiss him by just saying "kiss me." She's freaked out and the article is canned. Later he goes to see Clark and again shows off his power by making Clark choke himself. Clark must play in the game, and if he tells anyone his friends will all be hurt.

How it ends up: Chloe tells Clark that Mxyzptlk can control people's actions. She slowly begins to regain her trust with Clark after the whole Lionel transference thing. They find out Mxyzptlk is from a bloodline of people who can control luck. The only way to stop him is by jamming the frequency he uses to control people. Chloe's on it, Clark has to go warm up for the game. Jonathan stops Clark before he goes on the field, he still doesn't want him to play, but Clark says it's not Jonathan's decision, he has to do what's right. The old man's proud.

Chloe plugs a fighter jamming device, courtesy of her 3-star general uncle, into the PA system and adjusts the frequency to jam Mxyzptlk. Only he can hear it and it disables his ability to fix the game. He tracks Chloe down, but it's too late, the device has damaged Mxyzptlk permanently, he can't use his power. So, he decides to fix the game the old fashion way. He runs out on the field as Clark prepares for the final play of the game and tells Clark to throw the game or Chloe dies. Clark takes the snap and throws a pass... he then uses his super speed to run to where Chloe is, and save her, knock out Mxyzptlk and get back to the field before anyone knows he's gone. Oh, the pass, it's good and the Crows win the State Title!

After the game Clark's a hero, his parents tell him they've never been prouder of him, for well, everything and Chloe's talking to him again. Mxyzptlk was arrested, but Lex gets him out of jail and takes him to level 33.1 of a Luthorcorp building. He says he didn't bet against Mxyzptlk, he bet on Clark Kent. Now, he wants to help Mxyzptlk get his power back, and he tells him, he's not alone.

Everyone's happy at school, except Lana. Who's furious with Clark. Jason was fired and she thinks Clark ratted him out. Clark goes to see Lex, the only other person to know. Lex tells Clark Lana's not meant to be with Jason. Clark's not convinced, Lex has ulterior motives.
