Sisters Eliza and Sophie Roth own a Brooklyn jewelry shop together. Eliza loves joking around and putting diamond rings on her ring finger. One night she accidentally posts a photo of her wearing a diamond ring on Instagram. At first she is horrified, but then, after the sales start rolling in, that a glimpse of her life is good for business. She is then faced with a choice: does she come clean or continue with the biggest lie of her life?
