What Rhymes with Toxic -- Film Description:
"Chemical sludge is spilling into the lake. For the city councillor responsible, it's just a big nuisance. For the wildlife, it's a catastrophe. One turtle, in her desperate hour, summons up the courage to leave her home and speak truth to power. Turns out there's more at stake than just the lake."
