Bubblegum is a tribute to the generation of kids who grew up in Bulgaria during the 80s - collecting stickers from chewing gums and playing games outdoors.
The story glimpses into the lives of two kids, now adults - Kalin (35), a talented advertising specialist, and Biliyana (35), an adventurist with no particular direction in life, who meet again after 25 years. They spend five days filled with refreshing and fun childhood memories, finally remembering a promise they had made to each other in 1988.
