“Abyss” is right. Angus MacLachlan’s exercise in pointless unpleasantness opens with a couple in the throes of an office quickie, then devolves into a mushy stew of sexual jealousy, low-rent intrigue, and religious and ethnic intolerance. Histrionic, brassy real estate agent Erin finds the off-brand church that’s moved next to her office in a minimall distasteful, presumably because of some abuse she suffered in the past. She enlists her security guard/lover and his sweet live-in girlfriend in a scheme to somehow “send a message” to the church folks. Director Darrell W. Cox and his three plucky actors do what they can to enliven the material, but the major plot points are foreshadowed with the subtlety of a sledgehammer. The opening, then, is sadly appropriate: this show is like bad sex, the kind you hope will be over soon. Through 8/21: Fri-Sat 8 PM, Sun 7 PM. Profiles Theatre, 4147 N. Broadway, 773-549-1815. $13-$22.
