Vincenzo (Zachary Prince) reaches for Sarah (Megan McGinnis) in “Triangle”

Past roars up to the present. After discovering his lab is on the site of the 1911 Triangle Shirtwaist Factory fire, a high-tech scientist tumbles down a rabbit hole of discovery and memory as he unearths his own strange connection to several Jewish immigrants who perished there. “Triangle,” a dramatic musical from TheatreWorks Silicon Valley, will complete its run this weekend.

Through Aug. 2 at Lucie Stern Theatre, 1305 Middlefield Road, Palo Alto. www.theatreworks.org
