Tether

A chance encounter leads to Eric and Kate's discovery that any kind of pain they inflict on themselves can be felt simultaneously by the other person. While it starts out heavenly for their relationship, with all of their pleasure and senses magnified, their past tendencies soon begin to manifest and their connection traps them into situations they've never been before. Slowly, with the balance of power upended, their relationship takes a dark turn. After having grown numb to years of abuse and the pain of always being abandoned, Kate learns to exalt authority for the first time and begins to wield her ability to keep Eric under her control. Eric, on the other hand, experiences the helplessness of having no control for the first time. He becomes a hostage to the affair for fear of the pain she could inflict on herself and, by extension, to him.
