These are the broad outlines of “Peerless,” the playwright Jiehae Park’s sly and polished adaptation of “Macbeth.” Transported from the Scottish heath to the halls of a Midwestern high school, “Peerless” places the tragedy’s moral quandaries into the mouths and miniskirts of M (Sasha Diamond), a senior, and L (Shannon Tyo), her twin. L is a junior, having stayed back a year to increase their chances of getting into what they refer to only as “The College,” which accepts only one student from their school per year. But those plans go awry when The College accepts their classmate D (Benny Wayne Sully) instead. D has a lower G.P.A., but he is Native American. Though M is a girl and Asian American — “double minority,” as she puts it acidly — she believes that D outranks her in terms of racialized admissions policies. Smartly — because Park is very smart — the play is content to absorb the themes of “Macbeth” without providing corollaries for each of its plot points. There’s no Birnam Wood here, no spots to out. Macbeth’s bestie, Banquo, is now BF (Anthony Cason), M’s barely there boyfriend. Instead of the three witches and Hecate, there’s only a single classmate known as Dirty Girl (Marié Botha, delightful), costumed by Amanda Gladu in a witchy black trench coat. The set, by Kristen Robinson, shows a school hallway at an angle, with cutouts for a living room and a bed, as needed, while Mextly Couzin’s flashing, deep-hued lights nudge the environment toward the uncanny.
