The episode starts with Mordecai, Rigby, CJ & Eileen sitting on the couch watching an another episode of 'Mailin In It" when Benson enters the room reading the mail out loud. Benson tells Mordecai and Rigby they have mail and he gives them both a green square envelope. After reading the letters, it is revealed that it is an invitation to the 1000th chopper flight of Chopper 6. Everyone but CJ is excited as she states that she will be busy later since she is volunteering to clean up a river. Mordecai is disappointed but promises her to bring back some cake for her. Rigby says that it's a good thing she isn't coming since Margaret will be there, which prompts Mordecai to punch Rigby for saying it. CJ urges them to go there and have fun and Mordecai thanks her for being the best girlfriend and they both kiss.

The gang of three arrives at the party and is welcomed by Denise. They chat a bit and learn that one special guest will be able to ride the chopper for its 1000th flight. Frank arivess and immediately greets Mordecai and introduces his co-worker, Jackie Carmichael, who seems to be very determined to be that special flight guest. After a awkward introduction, Mordecai asks Frank if he can have a slice of cake for CJ. After learning that CJ is Mordecai's new girlfriend, Frank seems visibly angered, but he keeps his cool. Margaret arrives at the party with her news crew, which causes Mordecai to get nervous and excuses himself to the bathroom with Rigby following him.

Mordecai texts CJ a picture of the cake while hiding in the bathroom and CJ sents him the picture of her cleaning the river. Rigby knocks of the door and tells Mordecai to stop acting like this, but Mordecai states he can't screw up if he stays here. Rigby gets annoyed and promises to keep Margaret away from him during the party. Mordecai grudgingly accepts and Rigby punches him for punching him at the beginning of the episode. Rigby tries protect Mordecai from by causing trouble around the party as a distraction, which causes more tension and awkwardness between Mordecai and Margaret.

As the cake is about to be cut, Frank delivers a speech about how excited he is about this flight and how one lucky person will sit with him, his wife and Margaret on the chopper as it lifts off. Jackie gets cocky and gets on the chopper before he can say who the lucky person is, but he gets her off as he says the name Mordecai's name. Mordecai freaks out and grabs a slice of cake, but before he can try and leave, Frank explains how he was sorry for being a bit rude when he found out Mordecai had a new girlfriend and that he still feels Mordecai is a part of the family. Mordecai refuses to say no as he gets aboard the chopper and it lifts off within a few seconds. Margaret asks general questions while they are on board but Mordecai dodges all of them awkwardly. Margaret gets upset and scolds him for still being on the whole Christmas incident and states why can't she and Mordecai be friends. Mordecai lets out a sigh and then throws a casual joke, which lifts the tension between the two and they start to chat.

Back on the ground, Rigby and Eileen are viewing the chopper in the sky as CJ walks up behind them. Eileen is suprised as CJ says that as one of the participants got exposed to one of the chemicals dumped in the river, the clean-up drive had to come to a halt and she came to the party. She asks where Mordecai is and they tell her that Mordecai is in the chopper with Margaret. CJ looks closely at the chopper and sees Mordecai and Margaret sitting next to each other and laughing. She gets extremely angry and transforms into her storm cloud form. CJ starts to scream at Mordecai and Margaret while her storm pushes around the chopper. Frank activates autopilot and walks up to the cabin and asks Mordecai why his girlfriend is acting like this. Mordecai tries to explain but Denise falls off the chopper. Frank jumps out to save her and both mannonball safely into the pool. The storm is so severe that Mordecai, who is balancing the cake, accidentally loses balance and the cake falls into Margaret's mouth, which makes CJ think that Mordecai gave the cake to Margaret and gets furious and increases her storm, striking thunder on the ground and causes everyone to panic.

Margaret tries to get CJ's attention by grabbing a megaphone, but she slips and hangs on to one of the chopper's landing grip and armed with the megaphone. Mordecai tries to save Margaret, so he drops the cake that he has been holding this whole time. This angers CJ and her storm causes the chopper to go out of control. Margaret finally gets CJ to calm by saying that "I have a boyfriend" and she and Mordecai are just friends. Margaret's boyfriend, weekend sports anchor Dale Handland, arrives and CJ realizes everything is alright, stops the storm and reverts back to her normal form.

After getting the chopper down through Auto-Land, Mordecai retrives the small pieces of the cake that he dropped before and approches CJ with it. She tellsthat Mordecai she is sorry for not believing him. Mordecai requests her to have the cake, but she states that she's not in mood for having the cake and leaves the party with Rigby eating the cake meant for CJ as Margaret, Mordecai and Eileen watch CJ leave.
