The record company CEO thinks adding a fifth band member will broaden Big Time Rush's appeal and sticks the guys with a self-proclaimed "bad boy" named Wayne Wayne, who tries to inject dissension and tension within the group. Ultimately, Gustavo and the guys secretly band together to get him booted out of the band, in a "bad boy-off". Meanwhile, Mrs. Knight gets persuaded that there's an axe maniac on the loose, and forces Katie to play with a girl named Molly, who is later found to be a con actress that's 20 years old and tries to pass herself off as an 11-year-old girl driving in a high speed chase with cops, using Mrs. Knight's rental car, trying to get a job in Hollywood.

The boys are relieved to finally be able to spend some time apart after finding out that Gustavo is taking the day off. Logan is determined to get into a math lecture taught by Phoebe Nachee, but is disappointed when he finds out that the lecture is at an all girls school. Carlos panics when he realizes his helmet is missing, but gets a surprise visit from his father, a policeman, who accompanies him on the mission to retrieve his helmet. James decides to spend his day off trying to set off his acting career with the help of Camille. Kendall is desperate to spend time with his crush, Jo, but is discouraged when she continuously reminds him she has a boyfriend. However, when Katie finds out that Jo does not have a boyfriend, she tells Kendall, and he is determined to get the truth out of her.

The guys, who desperately want to remain in L.A., have to pass the greenlight of their demos for that to happen, after Kelly tells them they will be forced to head back to Minnesota if they do not get their CD's greenlighted. Mercedes Griffin, Griffins daughter, comes and pretends to be the "secret someone who picks the demos". They soon find out that the demos are picked by a chimpanzee, so they try to bribe it to pick Big Time Rush. Meanwhile, Mrs. Knight tries to be assistant manager to stay at Palm Woods for Katie's sake.

A heatwave strikes Hollywood and James starts to use tanning spray that's supposedly "mangerine" to the point of his skin looking orange. The boys find out that James has "Hollywood Fever" from Camille and when Gustavo sees this, he tells Kendall, Logan, and Carlos to fix James, or he will fire and replace him. Kendall, Logan, and Carlos go on a mission to get rid of the his tanning spray by chasing him around with water-guns. While on the mission, Carlos finds out that the one of the Jennifers went away so he joins their group and also catches Hollywood fever. Meanwhile, while Logan looks for James in Palm Woods Park, he runs into Guitar Dude who gives him a set of bongos and tells him to chill out, catching the fever and losing his uptight edge in the process.

The boys learn that Camille is leaving the Palm Woods unless she gets a part in an acting job, and must help her, eventually promising everyone a part in their upcoming music video. But Gustavo said Camille cannot be in the video, and Big Time Rush tell everyone that they can be in the video. They gotta figure out how to get everyone in the video, and Marcos tries to direct the music video but Gustavo will not let him. They stole Mr. Bitter's car for the video themselves, including all the people they promise and Marcos is directing, and the video's amazing. Gustavo asks Mr. Bitters to sell his car, and makes it Big Time Rush Mobile.

Big Time Rush returns to the Palm Woods after their world tour and learn they are now famous.

Because of the paparazzi and crazy fans, Gustavo moves the boys to Bel-Air, but the guys dislike the confinements of their new ritzy lifestyle and make a plan to return to the Palm Woods.

Kendall attempts to ask Lucy out on a date, until her ex-boyfriend Beau arrives at the Palm Woods to reunite with her. Moments later, he is caught also making out with other girls at the Palm Woods. With James, Jett and Camille to assist, Kendall is determined to document evidence of Beau's activity. Meanwhile, Griffin orders Gustavo to kidnap him, so Gustavo hires Carlos and Logan to do the job. Also, Mrs. Knight and Katie (with help from Buddha Bob) try to steal Jett's computer to find out the ending of the cliffhanger episode of New Town High which Jett is on.

Kendall is unsure whether he has moved on with Lucy during Jo's absence, or whether he still has feelings for Jo. Meanwhile, Carlos has to make a choice to stand by either his best friend James, or his new benefactor Mr. Bitters, during a supposed zombie apocalypse.

Camille finds a gold necklace and believes it's Logan anniversary gift to her, when it's really Kendall's birthday gift for Jo. Meanwhile, James and Carlos want to find out if they can listen to BTR in pure gold without getting caught by Gustavo.
