Marya Sea Kaminsky plays Rachel Corrie, the irrepressible young American who lost her life attempting to protect a Palestinian family's home in the Gaza Strip in 2003. Like the best nonfiction-as-art, what you already know going in is acknowledged in subtle, brilliant ways, like when, as Corrie nears her death, Kaminsky climbs on top of the set and looks down on the earth below her. She, of course, doesn't know what's coming. (Seattle Repertory Theatre, 155 Mercer St, 443-2222. 7:30 pm, $10—$40.)
