Two modern women accidentally time-travel to the seventies, becoming bullied sisters-in-law. Facing a biased mother-in-law, a spoiled sister-in-law, and toxic relatives, they join forces to strike back, using modern business thinking to make braised food and set up a street stall to start a business. From seeing through formula traps to fighting against malicious suppression, they resolve crises with wisdom and courage, ultimately establishing the "Sisters' Fragrance" Food Group, leading the entire village to common prosperity, rewriting their destiny with their own hands, and living out a wonderful life of their own.
