To remind the world of the millions of birthdays around the Christmas season, Coca-Cola collaborated with the residents of Cascais, Portugal, to prepare a surprise birthday party as big as the community. Unaware of anything, Olivia, whose birthday falls on December 22, embarks on a celebratory journey guided by her sister, encountering friends and family members along the way. The pinnacle of the celebration happens with the arrival of the Coca-Cola Christmas Truck, marking the emotional reunion with her best friend, Leo, who traveled from Tanzania to join her for the first time in 10 years. The whole surprise party was broadcasted live on Olivia’s birthday.
