Emily is drugged and locked inside a drilled shipping container by her husband Mark and best friend Sophie, then thrown into the ocean. Pregnant and alone, she fights for survival—drinking rainwater, eating raw fish, and building tools to stay alive. During a violent storm, she gives birth to her daughter, Grace. After seven days, she sends out distress messages in bottles and is finally rescued by her brother Daniel. Meanwhile, Mark and Sophie’s plot unravels at their wedding, where Emily and her family expose their crimes. The two are arrested in disgrace. Emily, holding her baby, finally returns home.
