Waldek, an overweight 10-year-old boy hailing from Grochów, harbors an intense fascination with the world of video games and nurtures lofty dreams of becoming a professional esports player. His journey finds him participating in a series of tournaments alongside his dedicated team, known as “Three Kings,” which includes his two close friends, Staszek Siemek and Rudy. Supporting his passion wholeheartedly is his overprotective mother, Teresa Banas, whose encouragement fuels his aspirations.

The story takes a twist when Mariola, Dorota Kolak, Teresa’s eccentric aunt, arrives for a visit. Waldek cannot shake off his perception of her as “mentally unstable,” leading to considerable annoyance, especially when she stays at his home while Teresa goes for a hospital appointment. Over the course of the day, Mariola imposes new responsibilities on Waldek, compelling him to ride his bike, wash dishes, and even prepare his own meals. The hassle becomes overwhelming, causing him to eventually doze off while engrossed in a gaming session with his pals.

Feeling burdened by Mariola’s unrelenting antics, Waldek makes a desperate decision to sneak to the hospital in the dead of night to check on Teresa, only to be met with despair upon discovering the gravity of her condition. Meanwhile, after Rudy departs the team to pursue a more professional path, Waldek and Staszek find themselves on the hunt for a new teammate. It is during a visit to a local swimming pool that Waldek meets Delfina, who immediately captures his attention and stirs unfamiliar feelings within him. Initially disapproving of her, Staszek’s demeanor changes once he learns that Delfina is also an avid esports player, and the trio eventually welcomes her into their ranks.

Mariola seizes the opportunity to take the new recruits on an adventurous day trip, where an anxious Waldek attempts to confess his feelings to Delfina. However, his endeavor ends in disappointment as she rebuffs him, an outcome influenced by Staszek, who also harbors a crush on her. Heartbroken, Waldek discards her application to join the team in a fit of frustration, crumpling it up and tossing it away.

Further complicating matters, a visit to his grandfather’s house causes a rift between Waldek and Staszek, prompting Waldek to step back from video gaming altogether. Instead, he spends time engaging in various activities and chores alongside Mariola, who, despite her quirks, is steadily becoming an ever-present figure in his life.

Eventually, Staszek returns to mend their friendship, aiding Waldek in navigating the aftermath of their conflict. As their bond strengthens, Waldek finds solace in the news that his mother’s condition has improved, a revelation that brings hope. He is pleasantly surprised to learn that Mariola has taken the initiative to submit Delfina’s application. With renewed enthusiasm, Waldek rebrands the team as the “Queen and Kings,” and their hard work pays off when they receive an invitation to participate in a prestigious esports tournament in Cologne.

As the moment unfolds at the airport, both Teresa and Mariola beam with pride, watching on joyfully as Waldek, Staszek, and Delfina prepare to board their flight to Germany, brimming with dreams of conquest in the esports arena.
