In 1936, Hungary’s championship team, escorted by their captain, Count Szirmay, retreats to a lakeside villa after a triumphant win in London, only to discover that a runaway English bride, Gingi Cheswick, has stowed away among them. Tasked with returning her home, serious young Gyurka Károlyi finds himself reluctantly drawn to her, while the team’s prankster Blazsek engineers a series of comic mishaps. Reunited under the strict watch of a girls’ institute and pursued by Gingi’s determined father, Gyurka and Gingi must navigate misunderstandings and rival suitors. Their story culminates on the playing field, where Gyurka’s unexpected heroics secure both a sports victory and the approval needed for their romance.
