As the dutiful daughter of a community health worker, she is on track to fulfill her father’s dream of becoming their island’s only physician.

After she lies to her father, accepts a position at MIT, and meets a similarly impassioned Chinese American scientist, she has a buzzing feeling that her two worlds are about to collide.
