In a neighborhood called Dowisetrepla, Marshall falls in love with the first apartment that he and Lily visit. Lily feels guilty because of the huge credit card bill she hides from Marshall and because she knows they can't afford the apartment. Robin urges Lily to tell Marshall about the debt.

The next day, Lily and Marshall go to the mortgage broker and apply for a mortgage, where Marshall finds out about Lily's debt. Later, Ted, Barney, and Robin go home, where they follow the clues and discover that Lily and Marshall were having a fight. Lily and Marshall return, exclaiming that they bought the apartment. The next day, Lily and Marshall take a taxi to their new home, where they find out what "Dowisetrepla" is an abbreviation for.

Meanwhile, Barney hooks up with a woman, Meg, and takes the girl to the apartment in Dowisetrepla so he can sneak out while she is in the shower.
