Equity is that rare thing: a Wall Street-set movie that focuses on women. It’s also directed and written by women, also still rare. Three of them make up this story: Naomi, her younger associate Erin ( Sarah Megan Thomas) and Samantha ( Alysia Reiner) , a Justice Department investigator and former college acquaintance of Naomi’s, who’s looking into cases of financial crime — and is intrigued by Naomi’s close relationship with Michael ( James Purefoy) , a broker at Naomi’s firm.
As Naomi reels in a tricky social-network IPO, with Erin’s breathless assistance and under Samantha’s watchful eye, questions arise: Are Naomi’s conversations with Michael insider trading or just office gossip? Will Erin’s pregnancy, which she’s trying to keep secret, affect her ambitions at the firm? Will Samantha say anything to find out what she needs to know — and does that make her unethical, or just a good investigator? Can any of these characters really trust each other?
