“Fire” is set at a Christmas party where two couples reveal the birth, progression, and possible death of multiple relationships. At times funny, at times sad, the beauty here is the cast. This is ensemble work at its finest. For the second portion, “Light”, the level of intimacy on display is breathtaking. Every simple head tilt or hand gesture reveals years of love, pain, loyalty, and betrayal. This is some of the most subtle work in immersive theater you may ever witness.
