Cole Theatre’s adventurous production of The Bachelors takes an unsparing look deep into the male psyche. It is not always easy to watch. 

It’s amazing how well playwright Caroline McGraw manages to capture the flavor of men’s behavior when they are away from women. (Was she hiding behind a couch?) Whatever the answer, this rising writer is as much the star in a challenging theatrical event that should not be missed. (It runs through April 10.)

The Bachelors plot carries little action in the conventional sense: three 30-something men are still living a frat style life, long past the period of respectability. The play reveals one of them has used a date rape drug to prey on a young woman, who is gagged and naked in an attic room - a shocking turn of events.

As the play opens, Laurie (Shane Kenyon in a very strong performance), returns from a Vegas business trip to find Kevlar (Nicholas Bailey) dead drunk on the floor, the house trashed. Laurie helps Kevlar sober up, when Henry, the third roommate, arrives. 

As Henry appears (Boyd Harris excels as this menacing sociopath) we sense something is amiss. And these presentiments of danger unfold in the action. Henry is perturbed that Laurie has returned early, and that he has sobered up Kevlar. Henry has also drugged Kevlar, so he won’t learn about the woman in the attic, either. 

Laurie’s early return throws a wrench in Henry’s nefarious plans. Laurie is intent on rescuing the woman in the attic. A brawl follows, and Henry beats up Laurie. 

We should recognize these men as archetypes: Henry, alpha male with a cruel streak, is a biochemist; Laurie, feminist-male, is perpetually carrying the torch of unrequited love, and has just been fired from his sales job. 

The third, Kevlar, is a narcissistic wastrel. His current emotional trauma kicks off the play: he can’t understand why his long-time love left him after getting a terminal ovarian cancer diagnosis. The audience knows why: she doesn’t want to spend her remaining time with a guy like him, who could never commit, and provides little support.    

McGraw’s portrait of these males reveals the toxic mix of their personalities. What shows isn’t pretty, and there is little to redeem the characters. Like fruit too long on the branch, they have gone from ripe, to fetid. As the play closes, a foreboding wind blows open the apartment door - hinting at a dark destiny. 

The play is directed by Erica Weiss, and she has handled a difficult work well. McGraw's script has the characters shift from language that is realistic and natural, to soliloquoies that border on magic realism. One, a description of his lost love and the perfect girl, by Henry reels in the audience as they, and his roommates, realize this was someone who never existed. It's poetic. 

In another long interlude Henry performs a dance that mimes the strutting (and aggravating) a male displaying his dominance among men. It seemed over-long, but perhaps that was the point. 

The set is well-conceived, a kind of mindless squalor, with stairs suggesting those upper reaches that we don't want to see. 

The cast's Boyd Harris is Cole Theatre's artistic director. The Bachelors runs through April 10 at Greenhouse Theatre Center.
