In Canada, Terrance and Phillip barge into the Canadian Department of Mobile Games, confronting the Canadian Minister of Mobile Gaming and Prince of Canada. The Prince and Minister of Mobile Gaming try to pass off a charade but Terrance and Phillip see through it. They explain that they can make low quality games and use micro-transactions to make money and that it's all harmless fun.
At the Marsh Residence, Stan is being punished by his parents for spending $489 on the Terrance and Phillip mobile game. Randy Marsh blames his father's "demons" from his gambling addiction. Sharon Marsh says that maybe Randy also inherited those traits with alcohol. Randy denies it because he quit and only drinks Pabst Blue Ribbon and wine.
Back in Canada, The Minister of Mobile Gaming explains to Terrance and Phillip that the mobile game has to be barely fun so that the players micropay to make it more fun. He also entices Terrance and Phillip with money and the simple idea that everyone is doing it.
Later, Stan is confronted by Kyle, Cartman, and Kenny because of his addiction to the Terrance and Phillip mobile game. Stan inadvertently reveals that Jimmy told him about the game. Kyle, Cartman, and Kenny figure out that Jimmy has been telling everyone about the game.
In town, Kyle and the others confront Jimmy about pushing the game on people. He reveals that he has never played the game and is simply paid to push it to people.
In Canada, once again, Terrance and Phillip decide that they don't want to put out a freemium game because they are afraid people will spend too much money on the game. The Minister of Mobile Gaming presents the idea of using some of the money they are making in order to teach people to be responsible, citing the alcohol industry.
An advertisement for alcohol then plays, showing people having a great time while drinking and showing sexual imagery, only to be followed by the statement "Drink Responsibly".
At the Three Feathers Indian Casino, Randy is showing Stan Marvin Marsh's terrible gambling addiction. He then takes Stan and Marvin home to scold them some more. Marvin brings up Randy's alcoholism but Randy denies it. Stan and Marvin agree to quit together.
At the Valmer Residence, Jimmy explains to Kyle, Cartman, and Kenny that he needed the money to play another freemium game and that the companies make you pay on purpose.
That night, Stan is trying to sleep, but the Terrance and Phillip game keeps taunting him and he eventually obliges. He spends $26,000. Randy scolds him yet again, citing that just because he is Lorde doesn't mean that Stan can spend this money.
Stan goes to the Kyle's house for help and Cartman, Kenny and Jimmy come over. Jimmy, while alone with Stan, tells him to ask a higher power for help. Meanwhile, Kyle, Kenny, and Cartman are trying to figure out how to get the word out about Canada using pushers. Cartman simply tweets it and it starts to trend.
In Canada, Terrance and Phillip confront the Minister of Mobile Gaming about the pushers. The Minister of Mobile Gaming explains the real reason for freemium games. He explains that a small percentage of people pay for freemium games and it's those people who have problems with addictions. Terrance and Phillip won't stand for this.
Later, Stan starts praying to a higher power. Suddenly, Satan appears to tell him all about addiction. He explains that Dopamine is released when doing something pleasurable. In nature, this happens when you survive and sex, but since humans can easily survive and have sex, they get their Dopamine from addictions. If you are addicted and use too much, you need more and more to get Dopamine, meaning that Stan is just a normal human being.
The Minister of Mobile Games continues to explain that they are building a new Canada with micro-payments, finally revealing he's the Canadian Devil, or Beelzaboot.
Satan is explaining that Stan's genetics, from his father, are also a factor in his addictive personality. Stan's iPhone goes off and Satan checks out the Terrance and Phillip mobile game, stating it's different when something isn't fun. Stan tells him that Canada put the game out and Satan immediately knows the Canadian Devil made the game. Satan asks to borrow Stan's soul and Stan allows him to. He possesses Stan's body and makes his way towards Canada.
In Canada, the Canadian Devil now has complete control over the souls of every Canadian. However, Satan in Stan's body fights with the Canadian Devil. The fight leads to the entire area being blown up by Satan and sucked into Hell.
Kyle, Cartman, and Kenny are playing basketball, when Stan rises back from Hell and walks off without issues.
Terrance, Phillip, and the Prince of Canada hold a press conference and declare that Canada will not make freemium games and will not use the money from addicts to help themselves. Canada will still be an ethical, respected, "shitty" tundra.
Later, Stan and Marvin are playing board games in order to keep themselves clean. Randy shows up and decides to join them. He asks them if they want to put money on it.
AV Club gave "Freemium Isn't Free" a "B-" rating saying: "And yes, I get that the episode was trying to draw a line between freemium games, gambling, and alcohol addiction, but that all seemed like a bit of a stretch. I’d rather South Park get to the business of making me laugh rather than teaching me about the ins-and-outs of mobile-gaming’s nefarious moneymaking strategy. Which isn’t to say this episode didn’t make me laugh at all—it definitely had some funny moments. I’m a sucker for any appearance by Canadians and Satan, so it’s nice to get an episode with solid moments from each."
IGN gave "Freemium Isn't Free" a "7.5" rating saying: "This week's South Park featured a clever setup, with Canada exploiting the freemium game phenomenon in order to renovate their own country. However, much of this episode was wasted on longwinded explanations of freemium games and how they worked. (A largely unnecessary subplot involving Jimmy didn't help matters.) That said, the episode picked up steam when Satan arrived to help Stan and later do battle with the Canadian Devil himself: Beelzeboot!"
