You never know what's going on behind someone's groove.

New York City, April 2002: Geneva, Crystal, Noah, and Chevy, a close friend group, are all mid-thirty, flirty--and ready to embrace the heat of the summer.

But behind closed doors, each of them has struggles of their own: Geneva keeps accidentally falling for the charms of her good-for-nothing ex-husband; Crystal is a high-flying executive with a picture-perfect life and a boyfriend who might just be too good to be true; Noah is attempting to keep the spark alive between him and his European boyfriend, but the flames of temptation keep catching fire in the most unexpected of places; and then there's Chevy, who couldn't care less about love and only wants a life of champagne dinners and designer bags, no matter the cost.

But as the city heats up and tensions keep bubbling under the surface, Chevy gets entangled with a hot and mysterious stranger. The group must come together to save their friend before it's too late--and before secrets break their forever friendship.
