But then Zoey and her roommates find out it is actually worth over 10,000 dollars, and they debate whether she should give it back to Chase or not. Zoey eventually decides that she should.

It's time for the national Blix Van Contest, a contest which takes place at several high schools across the country. The rules are easy: whoever has their hand on the van the longest, wins a trip for two in a private Blix jet to anywhere in the world. Logan fakes a broken leg in order to sit in a chair during the contest and sabotages his opponents. Also, Michael and Lisa break up while still in the contest. Meanwhile, Mark points out that Quinn's breath smells when they kiss, leading Quinn to believe she has a breath problem. She naturally makes a mixture against it, which as usual has its downside.

Logan's friends make him realize that his dad's money isn't enough to get him into a good college, so he decides to start an extracurricular activity: Miss PCA, a beauty contest where the goal is for him to select PCA's prettiest girl.

Their friendship is put to a test when Lola thinks Zoey intentionally picked out a better dress for herself than she did for her.

Annoyed by that fact, he sets out to find something he can do that will make her laugh.

Logan buys a car which is worth 327,000 dollars with his dad's credit card, even though he is not allowed to drive, so he can make out with girls in it. But when his dad finds out, he is furious and strips him of everything related to money, including chequebooks and credit cards, and also all the stuff he bought for it, like the plasma screen, the laptop and the stereo. Now Logan has to learn to live without money for the first time in his life. Meanwhile, Michael bets Mark and Quinn that he can escape from being tied up in ropes, no matter how they do it.

Zoey is offered a chance to move to London with her parents.

Zoey is back at PCA, for one reason: To talk to Chase about what she overheard on the webcam, and to find out if she loves him back. However, there is one problem - Chase isn't at PCA anymore. He left the school and got transferred to Covington, Zoey's old school in England, so he could be with her. Since they still are in two different continents, they try to date over webcam.

Michael is depressed that Chase isn't coming back, but Logan decides they should make the most of it with the extra space they have.
