James, Carlos, Logan and Kendall get the opportunity of a lifetime when they are asked to head to Los Angeles and form a singing group. Once they are in Los Angeles, they must figure out a way to make Gustavo Rocque and Rocque Records happy in order to become a singing sensation.

The boys get a dose of reality when Kelly tells them they have to go to school at least four hours every day while they live in Los Angeles. While the boys want to go to the fun Palm Woods school, they learn that Gustavo has arranged to have their school located at the recording studio, so they are never far from his grip. The boys do whatever is necessary to take down the "School of Rocque" and go to the Palm Woods school. Meanwhile, an attempt from Mrs. Knight to home school Katie (Ciara Bravo) fails, so she tries to get Katie to act in a commercial to gain entrance in the Palm Woods, with the help of Mr. Bitters.

The boys are not thrilled with their boring apartment at the Palm Woods and hatch a plan to improve it when Gustavo creates a fun "fake" living area for them on a soundstage for an upcoming EPK shoot. The guys enlist the help of all their friends at Palm Woods to move all the cool games and gadgets from the set to their apartment.

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 guys chase the same girl named Jo, causing the band to fight. Meanwhile, James gets an allergic reaction to a body spray and Kelly (Tanya Chisholm) attempts to make him get an allergy shot, Gustavo gets a new personal helper named Freight Train, Katie has to write a report on her biggest hero and writes about Gustavo so she does not have to read anything, and Griffin wants a slow love song for the next song, but Gustavo cannot seem to figure out how to make the song work.

When Gustavo goes away for a few days to check out a new boyband called "The Windmills", the guys "mansion sit" for him much to Gustavo's dismay. After much discussion with Kelly, Gustavo allows the boys to "mansion sit" but they must follow his rules or else they are fired. Once at the mansion the guys think it will be an easy task, but what seems like a task they can handle soon turns into a "big time disaster" as things don't go according to plan. Meanwhile with Kendall and the guys away, Mrs Knight starts to fell less needed by her children, so Katie decides to help her mother out by pretending to be sick.

The boys are at the Palm Woods, severely injured. Camille asked them why they look so beat up if they just got their picture in Pop Tiger. The boys show their entire flashback from beginning to end: The boys were having their very first photo shoot as Big Time Rush. However, with Gustavo and Kelly doing community service for vandalizing Matthew McConaughey's mailbox, Griffin took over and makes them "space matadors with stuffy puppies". A simple photo shoot becomes a race for time and the perfect shot. Meanwhile, Katie and her mom are determined to get an autograph from teen hunk Dak Zevon, and Mrs. Knight starts to go a little nuts when the security guards are mean to Katie, so she (Mrs. Knight) gets all the fans of Dak and tries to barricade the door to Dak's recording room.

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.

When the boys find out they are not invited to their own party at Rocque Records, they decide to throw their own in the Palm Woods, since Mrs. Knight and Katie are off to San Diego, even though Mr. Bitters does not allow it. They call the party a 'social gathering', since there is no rule forbidding them, and the boys agree on only inviting 3 friends each. Kendall invites Jo, as his 'guest-friend-person-thing', while James invites the 3 hottest girls on his phone. It is unknown who Logan invited. Carlos cannot decide and ends up inviting the first 3 contacts on his phone and one of them is 'All Contacts' (Carlos thought it was "Al Contacts", thus inviting his whole phone). During the "social gathering," everybody in Carlos phone is now in the party which causes a big problem. Soon, Bitters is hunting for their party, so Kendall and Jo try to stop him before the boys get "3 strikes" and are thrown out of the Palm Woods. Both Camille and Mercedes arrive at the party trying to spend some time with Logan which causes a problem for him.

Also, Carlos and Katie name themselves Robin and Hoodie, and try to find other ways to get their favorite fruit snacks, fruit smackers after Bitters makes the price insanely high so everyone cannot afford to buy them.

The boys hold their annual prank-day contest and the girls at Palm Woods want to participate, so it soon becomes a battle of boys vs. girls. Meanwhile, an awry prank-themed day with Gustavo and Kelly escalates into minor destruction and some violence. Logan becomes Dr. Hollywood's assistant for the day after his eyes got hurt because his own prank backfired on him. At the end, the prank war ended with Kendall and Katie as the champions.

The boys are excited to head back to Minnesota for the holidays, but hours before their flight, Griffin, the head of the record label, insists on them recording a Christmas EP, and will not let them leave until it's done.

Kelly and Kendall team up to help Gustavo return to his regular, angry self. Meanwhile, Logan downloads a Swagger app on his phone, which increases Logan's swagger and decreases James', causing James to almost "die" from dangerously low swagger counts. Carlos takes advice from a parrot, and when he is about to go on a date with a girl, the parrot tells him he has 24 hours to live, horrifying him and leaving him to live in the bathroom (Panic Room) of the apartment.
