The Enterprise encounters a mysterious life-form that entraps the Enterprise in its gravitational field. None of the Enterprise's engines or weapons can be used to free the Enterprise before the ship is dragged by the entity into a cosmic string. Meanwhile, Troi discovers that she is empathically blind and resigns as ship's counselor because she feels she is unable to perform her duties.
