Isaac (Zach Gibb) comes home from Afghanistan after three years to find his dysfunctional family in absolute chaos.

His sister, Max (Will Malloy) is now as transsexual.

His abusive father, Arnold (Jim O’Brien) has suffered a stroke, is dressed as a clown, and is controlled with estrogen milkshakes by his controlling wife Paige (Jennifer Mischley).

Isaac has some baggage of his own, having been dishonorably discharged due to drug issues.

The house is a mess. Clothes, books and household items are strewn everywhere. His father is sleeping in a cardboard box.

Mother Paige has taken control of the “new Regime”. She spouts her theories on sex, religion, racism, and her child’s transsexuality. She calls it Radical Reimagining.

Isaac is determined to bring the family back to some sense of normalcy, whatever that is, by gaining control of the family from his mother, who is not willing to concede.

Paige leaves the house to visit a museum, and Isaac goes to work. The first act ends, and he goes to work cleaning and rearranging the house. (The stage crew works hard and fast).

Paige returns and conflict takes over.

Paige spouts her theories. Isaac challenges them. Max adds his/her radical thoughts on gender.

Arnold sits there with his nightgown, wig and face painted, Isaac fights to bring him some dignity.

Soldiers come home to a different world with their own secrets, author Taylor Mac tells us. Mac suggests much more during this two-hour, R-rated play.

If you are easily affected by profanity, sexual references, drugs, violence, and racism, this is one you might skip.

I found much on which to ponder as Mac raises a multitude of issues, allowing the audience to decide where they stand.

The acting is excellent, especially Zach Gibb, who makes you feel his raging anger and confusion. Author Mac has him vomiting a bit too much, but in another scene a moment of violence resulting in a bloody nose is as realistic as I’ve ever seen on stage. (Credit to director Brien Lang, who has caught the essence of this challenging play.)
