In this episode, Veronica is hired by a Russian mail-order bride who requests her help in finding a long-lost love. Meanwhile, Veronica must help her friend, Meg, deal with a secret admirer while simultaneously guiding Logan through the possibility that his mother, Lynn, may still be alive.
Veronica talks to Logan about his mom's credit card use. Meanwhile, Duncan organizes an 1980s-themed dance. While they are talking, Meg walks up and tells her that she has a secret admirer. Meg asks for her help. Veronica walks into Mars Investigations, where a woman named Katerina asks Veronica to find her fiancé. Katerina explains the situation—they met online, but they have lost touch, and she thinks that he is in Neptune. Veronica asks Wallace to track one of the two boys who possibly texted Meg, and he agrees. The next day, Meg receives some flowers from her secret admirer. Veronica reports back to Katerina that they haven't found Tom (her fiancé), but Katerina agrees to pay more. Veronica places a fake casting call to pinpoint Tom, which she does. Logan's mom's credit card shows up with another charge at a hotel. Logan and Veronica attempt to enter the room in which her mother is staying. They are denied access, but Logan decides to stake out the place until the situation is resolved. Veronica visits the flower shop, but the staff member is unhelpful. Veronica finds out that Tom's dog is named Steve and decides to track the dog down.
Veronica contacts local animal hospitals and eventually finds one with a Catahoula Leopard Dog named Steve. She pretends to want to breed "her dog" with Steve, the dog's owner refuses to speak to her. Veronica visits Leo D'Amato, who agrees to call the numbers that the vet called. Meg goes to a party, but they find nothing in terms of her secret admirer. Logan continues to camp out in the hotel lobby. After Veronica appears, Logan sees someone who he thinks is his mom. However, it turns out to be Logan's sister Trina, which whom Logan has a tumultuous relationship. After Trina leaves, Logan breaks down crying in Veronica arms after realizing that his mother really is gone. On Keith's own insurance fraud case, he is being followed by a group of men in a silver Chevrolet. Keith eventually steals the car, also seeing that it belongs to someone named Yevgeny Sukarenko. Veronica goes back to the flower shop, bringing a sketch artist to aid the owner's memory. Leo gets back to Veronica and mentions three names. Veronica recognizes the third name and is about to call Katerina back with the news before Keith stops her. It turns out that "Katerina" is actually Yelena Sukarenko, the wife of the criminal who is actually trying to track down Tom because he testified against her husband and has changed his identity through the Witness Protection Program.
Under Keith's instructions, Veronica tells Yelena a fake address. Yevgeny and his associate go into the fake address (the model home of Meg's party), where they are promptly arrested by Keith, Leo, and others. Veronica receives the copy of the sketch of the secret admirer (Duncan), although she doesn't tell Meg this. However, at the dance, Veronica allows Duncan to approach Meg. Veronica goes back to her car and breaks down until Leo appears and invites her back into the dance. Soon, the two see Logan, drunk and acting strange, charging through the room in a dress shirt and briefs. Leo kisses Veronica. Veronica receives several calls from an unknown number, which is actually a pay phone that her mom, Lianne, likely used. She goes to the pay phone and finds her mom. She tries to get her out of the bar before seeing Clarence Wiedman looking at them.
