Montreal is in the grips of one of its summer heat waves, when searing
temperatures have a way of making its residents cast aside their better
judgment. A young twenty-something works the night shift at a call
center, her only company the disembodied voices of the customers who
call in to complain. She spends her night off drinking with her friend
Louis at "their" bar, while her successful boyfriend sleeps. His career
allows her the pleasures of his spacious, modern condo, a new existence.
She likes feeling undefined, still up for grabs, even as the
middle-class trappings of her relationship threaten to shape her. In the
stifling humidity of such surroundings, her life is turned upside down
when she grows obsessed with Mia, a beautiful woman she meets one night
at the bar. Then there's the woman who's gone missing, whose face is
constantly on screens across the city. How can she stem the drift away
from her relationship, she worries, when her former lover B., who was
both violent and magnetic, is always in her thoughts? All these orbits
are set to collide, as the heat wave shows no sign of breaking and
emotions reach record highs.
