Wen Zhaotang is stranded on an island by accident and confined by Xiwei Yaoting, a ruler consumed by obsessive possessiveness. She becomes Mrs. Xiwei in name only. The island is a cage at every turn: if she fails to escape, she faces water-cell imprisonment and electric shocks. The servant Xiaoyuan was once sold here and has witnessed firsthand the island's relentless, merciless control.
Wen Zhaotang never gives up on escaping. She secretly forges documents and conspires with her first love, Pei Shang, to return home by boat, promising to take wedding photos by the sea as soon as they come ashore. But every attempt is thwarted, and Xiwei Yaoting drags her back. He threatens Pei Shang's life to force her to yield and obey, even using childbearing as a bargaining chip in his hostage exchange.
