Krong Kam (Thai: กรงกรรม; lit. 'Cage of Karma') is a 2019 Thai TV drama that originally aired on Channel 3 starting from February 26 to April 30, 2019 for 19 episodes.

The whole story took place at Chum Saeng, Nakhon Sawan, in 1967. Yoi (Mai Charoenpura) is a middle-aged Thai woman who married into a Thai-Chinese family. She vowed to personally see to it that her family of six honour the Beh (Chinese: 馬) ancestors. She amassed a fortune in family businesses that consist of a grocery and the grain store, a rice mill that her husband runs, and various farmlands and properties across Nakhon Sawan province. She is foul-mouthed, irritable and a skinflint. She and her husband have four sons. All members of the family, including employees and Chum Saeng people, were fearing her.

One day, her eldest son, Chai (Thakrit Tawanpong), returns from the army with a pregnant prostitute Renu (Ranee Campen) as his wife even though he already has a fiancée, Philai (Pitchapa Phanthumchinda). Yoi rejects this and tries every possible way to make him leave Renu but fails. Unknown to her, Renu has performed black magic to tie her son's heart. She decided to marry her second son Tong (Chanathip Phothongkam) to Philai to avoid shame even though he likes a worker named Chanta (Preeyakarn Jaikanta) and also chooses to give Tong the house and store that she was supposed to give to her eldest. Her third son Sa (Jirayu Tangsrisuk) is the kindest. He is handsome, smart and charming. When Yoi finds out he has feelings for Chanta, she worries he will imitate his eldest brother. She decides to marry him off into a rich family. Unknown to her is that the family is tricking him into marrying their already pregnant daughter to avoid shame.^[1]
