Ted tries a rain dance in the hope that rain will keep Robin from going on a camping trip with Sandy Rivers. Lily is accepted at her internship, and she and Marshall break up.

It’s Ted’s 28th birthday and he still keeps looking for the perfect girl. Apparantly he is about to find her since the matchmaker he once hired to find him a partner has finally found the perfect match.

When he is about to meet her, Lily calls him because she is in trouble. Marshall gets himself into an office war between Barney and some guy named “Clark Butterfield” in which the guys do all kinds of gross things to each other.

Marshall and Lily finally have got the perfect place they always wanted to get married at. The only problematic thing about this is that the place is only available in two months. So, this means a lot of work for everybody.

To listen to a band Marshall wants to play at the wedding, Lily,Barney and Robin sneak into a High School prom. While the other three are at the prom, Marshall and Ted, who had actually planned a “men’s night”, are wrapping up wedding invitations until Lily wants Marshall to come to the prom to. Of course, Ted comes along too.

Robin invites everybody to a banquet and Ted is insecure about bringing a date or not. Barney hooks him up with a girl that seems to be a prostitute while Robin brings a real date.

Ted pretends to be cool with the fact that Robin has moved on, but Robin’s date is her sleazy colleague Sandy Rivers whom Ted and Marshall constantly make jokes about when watching him on TV. With all these people in the same room, the evening seems to be getting interesting.

After having quite a rough day and being a little drunk, Robin calls Ted in the middle of the night and asks him if he wants to come over to her place. Ted, of course, says that he will come.

On his way to Robin’s apartment, Ted starts to ask himself if it is okay to go to Robin since he still has got his girlfriend Victoria and asks his friends for advice.

After a month of long-distance-relationship with Victoria, she’s already sent Ted three care packages full of stuff he likes, but he hasn’t sent her any. Marshall works in Barney’s office and doesn’t like it all or the people he works with, but Barney talks him once again into keeping the job.

Marshall decides that it must be easier to work in the office if he adapts to the people he is working with and gets some “get psyched” training from Barney.

Victoria is about to leave to go to Germany for two years for a donate fellowship. Ted doesn’t know if he should her ask to stay or if he should tell her to leave. Marshall needs a new suit and Barney helps him.

Meanwhile, Robin and Victoria accompany Lily to a wedding dress fitting and also the girls talk about whether Victoria should leave Ted or not.

During a game night Robin gets to meet Victoria. What actually was planned to be a funny night turns quite serious when Barney’s former love Shannon gives an old tape to Lily which shows the “real” Barney.

While watching the tape an embarrassed Barney storms off. When he returns, Barney tells a story from 1998, when he seems to have been a whole different person, and what made him the person he is today. To make Barney feel better, all others also tell their most embarrassing stories.

Ted and Victoria had decided to wait for one month before sleeping together, but Victoria forgets that she’ll be out of town on that day. Meanwhile Marshall and Lily celebrate their nine year anniversary, and Barney and Robin have a bros night out.

Ted meets a beautiful woman named Victoria at Claudia’s and Stu’s wedding and they spend a great time together that night. Unfortunately, Ted and Victoria made a deal that they will never see each other again after that night and they do not exchange telephone numbers or anything else.

The morning after the wedding party, Ted wants desperately to see the girl again. So he starts searching for her and asks anyone from the wedding who could have possibly know her, but she seems to be lost.
