Health problems and mother issues are the topics; an unreliable narrator and plenty of “theatrical devices” are the approach. Elisabeth Nunziato is Lisa, who is caught between skepticism and empathy for her mother’s (Polly Adams) mystery illness, and she has her own problems to boot. T, W 7pm; Th 2 & 7pm; F 7pm; Sa 8pm; Su 1pm. Through 12/4. $18-$30. B Street Theatre, 2711 B St.; (916) 443-5300; www.bstreettheatre.org.
