Storm in a Cocoon (; literally "Property Protector"), is a Hong Kong pre-modern serial produced by TVB, starring Steven Ma and Tavia Yeungas the main leads. Filming for this series took place in Shunde and Hong Kong.
Synopsis.
The boss of Shunde's largest silk factory "Wing Tai Lung", Poon Wing Lin (Elliot Ngok), has decided to pass down the business to his eldest son, Poon Ka Hin (Evergreen Mak) and second daughter, Poon Hau Yee (Akina Hong) due to his old age. However, Hau Yee unexpectedly commits suicide. When third son Poon Ka Yeung (Steven Ma), a military doctor, returns to help run the business, he begins investigating Hau Yee's death as he suspects her death was not a suicide. As Hau Yee's best friend, silk factory worker Tong Bing Bing (Tavia Yeung) also shares Ka Yeung's suspicions and joins him to find the true cause of Hau Yee's death. As their search goes on, they unfold a number of complex relationships between the Poon family and its factory workers, particularly Sin Bik Suet (Maggie Siu), the senior worker in the factory who contends with Bing Bing's behavior, and Fung Chi Chung (Natalie Tong), a duplicitous young woman who enters the factory with secrets of her own to hide.
As Ka Yeung and Bing Bing spend more time together, they gradually develop feelings for one another. However, their relationship is complicated by the reappearance of Bing Bing's long-long fiancé, Kwan Jo Yiu (Raymond Cho), who brings more trouble than everyone anticipates. As they come closer to finding Hau Yee's murderer, the Poon family faces retribution and Ka Yeung and Bing Bing struggle to protect the Poon family's property, not realizing the murderer is much closer to them than they expected.
Though Hau Yee's murderer is apprehended, "Wing Tai Lung" later faces a new danger with the arrival of Chiang Chi Yan (Cheung Kwok Keung), who intends to manipulate and destroy the Poon family by first convincing Ka Hin that he is actually Chi Yan's son and not Wing Lin's son. Believing that Wing Lin's constant criticism of Ka Hin's ability to run the business stems from Chi Yan's claims, Ka Hin willingly takes part in the plan to destroy the Poon family. Ka Yeung and Bing Bing risk everything in order to stop Chi Yan, Wing Cheung and Ka Hin before it's too late.
