Lin Xiaoman, an algorithm engineer for the navigation app StarPath, has dedicated her life to pursuing "zero deviation"—until a bug in her code causes outdoor surveyor Lu Zhao to miss a critical measurement, sparking a feud. But strange occurrences follow: every time Xiaoman works late, the app "mistakenly" leads her to the convenience store Lu Zhao frequents; when Lu Zhao helps his grandma find her old house, the coordinate deviation points straight to Xiaoman's childhood home. They soon discover those "deviations" are actually a "secret code" Xiaoman wrote as a kid—she hid the coordinates of the boy who saved her back then into her algorithm, and Lu Zhao is that boy. When "zero deviation" meets "the error of heartbeat", they realize: the most accurate navigation is never a point on the map, but the direction where their heartbeats align.
