Sisters of Pearl (2010)

Description:

After the death of her husband, Chu Pik Ha returns to her maiden home with her son, in a deliberate attempt to take over the family jewelry business from her elder sister Chu Pik Wan. To prevent Ha from getting too out of hand, Wan needs her husband Ho Cheung Hing to create trouble for her sibling. Hing does not follow her instructions, but instead secretly helps Ha tackle her problems one by one. Wan soon comes to realize that Hing has never really got over Ha. Wan's younger sister Chu Pik Lam is still attending school and is too young to deal with such family issues. Wan feels a profound sense of helplessness and becomes even more frustrated when So Lai Sheung turns up suddenly claiming to be a mistress of her late father and pregnant with his baby. Out of respect for their father, the sisters agree to put Sheung up for the time being until the situation becomes clearer. Shortly thereafter, Ha discovers that Sheung is just a tool of Sang guy who has been plotting to wage a battle of will against the Chu's.
