You see a dozen shows by Neil Simon, you think you’d know what to expect – the farce of Rumors; or goofy relationships of The Odd Couple; or sweet (and a bit bitter) memories of Brighton Beach; or hilarious razor wit of Goodbye Girl.

For those unfamiliar with “Lost in Yonkers,” Simon’s 1990 Pulitzer-winning play presented by Main Street Productions in Westfield, note that many of his comedies’ hallmarks are present, but with a dark edge that is too real to completely laugh away. With the sharp rap of Grandma’s cane, wisecracks cease. The exaggerated aspects of characters come not in caricature but from coping with lifelong trauma.

In 1942 (America’s first full year in World War II) Eddie Kurnitz (Matt McKee) has to settle debts from his wife’s fatal battle with cancer, so takes a traveling job gathering scrap metal for the War effort. Thus he leaves his sons, 15 “and a half” Jay (Drake Lockwood) and 13 “and a half” Arty (Finley Eyers) with his mother in Yonkers (just outside New York City). Grandma Kurnitz (Lisa Warner Lowe), who escaped from Germany years ago to raise Eddie and his siblings in as strict and unsentimental a manner as possible to prepare them for what she sees as an unrelentless cruel world, is unpleased with his plan, but tolerates it at the request of Bella (Becca Bartley), her daughter whose ever-diverting mind stays in a childlike state.

Grandma owns and runs the candy store on the first floor of their building, which ironically becomes hell for the boys who find themselves penalized for every morsel that goes missing, whether it was their doing or not.

Meanwhile, Eddie’s brother Louie (Thom Johnson) shows up, with a wary eye out the window. He’s a bag man for shady characters who now want what he’s secreted in the bag. Gangsters being cool to teen boys, as well as the desire for cash to get his father out of debt and back home, Jay and Arty try to win his favor.

We also meet Aunt Gert (Maggie Meier), who has an unintentionally comical respiratory issue, when Bella gathers the family for what could be a momentous announcement if she can string the thoughts together.

Dark comedy derives a lot of chuckles from situational humor, and Simon serves that well here, but we are more drawn in by the layered drama of a family whose dysfunction runs deep, apt for one of the most stressful eras for any American. There is a method to the matriarch’s cruelty, and grudging admission of benefit, but it’s still difficult to justify. The damage is plain in every one of Grandma’s offspring, but especially Bella, as Bartley gives a brilliantly endearing and heartbreaking performance. Lowe, for her part, delivers both the cold exterior and fire within that keeps Grandma both feared and respected, with fleeting moments of wry German humor that keep us all off-balance. With Uncle Louie, Johnson maintains an air of Cagney-cool with just a touch of paranoia in knowing his gangland adventure ain’t a movie. Lockwood and Eyers keep the youths as smart-alecky and immature as you’d expect, but, as kids do, learning to adapt to their situation.

Jen Otterman directs, with assistance from stage manager Monya Wolf. The comfy but no-frills living-room set is by Ian Marshall-Fisher.
