Brian takes Stewie to a University library and witnesses a protest against a professor who told someone to have a nice day and they considered it microagression and also because someone put weird on the transgender bathroom. Brian Tweets and gets back into the Twitter game.
He goes to see the Baywatch movie and writes a tweet about Kevin Hart's new movie that's supposed to be funny but is offensive instead and the Twitter world goes crazy and overreacts. They attack Brian at the theater and at home so Peter and Lois ask Brian to move out because they are being ostracized by friends and the community.
Brian goes searching for an apartment and finally finds one.
He's living a lonely sad and pathetic life. All because of one Tweet.
