Writer and director Celine Song made her directorial debut with "Past Lives." In the semi-autobiographical film, Greta Lee plays Nora, whose family left Korea when she was a young girl and moved to the US. In the process, she lost touch with her childhood friend (and crush) Hae Sung (Teo Yoo). Years later, he finds her online, and they connect again in a series of long-distance calls before they lose track of each other again. The next time they link back up, Nora is married to Arthur (John Magaro). "Past Lives" is a story about fate, adulthood, growing up, and what it really takes to become who you are.
