The premise is smart: Elise, a grad student in biology, wanders into a physics lecture and ends up searching for the Higgs boson, a theoretical particle. What she’s really looking for is her missing sister.

But playwright, Caroline Sniatynski, gives us too much of the present-day story (which includes a chipper undergrad and a perky neighbour, both foils to Elise’s grief-stricken somnambulance) and too little about the sister’s disappearance.

More of the backstory might enable Leslie Dos Remedios to explore a wider range of feeling than the flat numbness we see here, especially since, under Ulla Laidlaw’s direction, she spends a lot of time miming staring at computer screens. More life, please.
