Caged (2011) ซับเวียดนาม

After years of suppressing her desires, Stella finds she can no longer ignore her deep-rooted longings. Breaking out of her cage and starting a secret double-life, Stella transforms into a "unicorn", a nickname for single women who indulge in a hedonistic lifestyle, visiting sex clubs and erotic parties, and flourishing with all the new attention. Even as her husband uncovers his Stella's secret life, he can't do much more than give her the freedom that she obviously needs, in the hope it's all just a phase. Then one day she finds herself lying unconscious in a basement cell, with no idea how she arrived there. Days go by when an other woman is brought into her cell. Christine, a woman about the same age. In the following days they reveal their life stories to one other. Christine is convinced that the reason for their captivity lies in Stella's lifestyle.
