In a flashback to 6 months previously, a Löwen named Don Nidaria (Phillip Keiman) kills his Maushertz wife, Katherine (Erica Sullivan), in an act of rage. In the present, Don's lawyer, Barry Kellogg (Brian T. Finney), uses his powers to spread a pheromone among the jury—of which Rosalee (Bree Turner) is foreman—causing them to agree with his statements.

Nick (David Giuntoli) encourages Monroe (Silas Weir Mitchell) to show Juliette (Bitsie Tulloch) the trailer. Juliette becomes confused by the strange books and the weapons. Suddenly, she begins seeing flashbacks of Nick to when he was trying to explain the Grimm world to her. Monroe finds Rosalee sick after attending court and offers to accompany her the next day. He watches as a witness changes her testimony, then follows as Kellogg goes to the bathroom to eat a toad. He realizes that Kellogg is a Ziegevolk.

Nick, Hank (Russell Hornsby), and Monroe attend the next hearing. They watch as Wu (Reggie Lee) changes his testimony at Kellogg's prompting. In the spice shop, Rosalee looks up an antidote, but it requires Kellogg's sweat. Along with Bud (Danny Bruno), Nick, Hank and Monroe set up a sting operation: Monroe chases Kellogg, who is "saved" by Bud, who gives Kellogg a handkerchief to wipe off his sweat and ascertains where he is staying. The next morning, Nick and Hank arrive and question Kellogg while Monroe sneaks in to inject the antidote into the toad. He is surprised to find two toads, and is forced to choose just one of them to inject.

Meanwhile, in Vienna, Adalind (Claire Coffee) tells Eric (James Frain) that Renard (Sasha Roiz) has failed to get the key. Eric decides to visit his brother. In the court, the jury finds Don guilty, shocking Kellogg. That night, while the group are celebrating their victory, Kellogg visits the spice shop looking for an antidote for his condition. Upon recognizing everyone in the shop, he realizes he has been duped: he woges into his Ziegevolk form and attacks Rosalee. Monroe rushes to protect her and starts to beat Kellogg, but is stopped by Nick, who arrests the lawyer. In the final scene, Juliette is at home, surrounded by visions of Nick at various times in their relationship, as her memory comes rushing back.
