In the 1980s, Lin Acai, a lonely widow, single-handedly supported her family and put her younger brother-in-law through school. After the village chief persecuted her and she fell off a cliff, she unexpectedly inherited ancient immortal medical and martial arts techniques. She rose to turn the tables and face-slap the wicked, then defied convention to be with her grateful, devoted brother-in-law. Together, they built a prosperous life and stayed by each other's side forever.
