Johnna Adams’ ‘Gideon’s Knot’ is not an easy play to sit through. The tense, 90-minute one-act is gut-wrenching, but also eloquent and profound. The drama focuses on a grieving mother and an emotionally overwhelmed schoolteacher who meet to talk about Gideon, the mother’s son, who may have been bullied or may have been the bully. Acted by Bay Area talents Taylor Bartolucci and Dyan McBride, the play comes to Napa for a five-performance run Jan. 20–24 at Lucky Penny Community Arts Center, 1758 Industrial Way, Napa. $21–$31. 707.266.6305.
