Li-Ann, a dreamer, is a strong believer of the soul mate theory and rejects all men, especially her best friend KS, until she falls in love with Jeremy, at first sight. They tour Chinatown, Singapore, together on February 29, 1980. Unfortunately, she is heartbroken when he tells her he is engaged. He decides to make up to her by meeting her at the same time, same place, every leap year. Their love spans 20 years, as they realize the pain of love until they take the leap of faith...and the leap of love...

"A promise to meet every four years."
