In her past life, at the funeral of her son Shen Yifei, Lin Suyun caught her daughter-in-law He Meilin and her husband's close friend Zhao Dehai conspiring to embezzle the Shen family property. Just as she was about to expose them, she was pushed down the stairs and killed by He Meilin, while her husband Shen Jianguo remained completely in the dark. Reborn back to the day of the funeral, Lin Suyun was determined to exact revenge. She pre-installed surveillance cameras and set a trap. As expected, Zhao Dehai and He Meilin seized the opportunity to meet secretly, and Lin Suyun lured her husband and sister to catch them red-handed on the spot. In a panic, Zhao Dehai hid inside a coffin, but his phone ringtone exposed his disguise. Even after being exposed, the two brazenly twisted the truth and accused her of framing them, but Lin Suyun held irrefutable proof, exposing the conspiracy in front of everyone and seeking justice for her son and herself.
