A confused straight guy and a gay hookup artist walk into a bar ... Firefighter Sean Connolly is straight - until one impulsive night changes everything. He tries to dismiss it as a fluke, but when a fire rescue leads him back to the guy who blew his mind, he's thrown into a chaos of confusion and want. He gives in to curiosity, exploring a new side to himself - not just his attraction to a man, but his desperate need to please. Paramedic Jace Gillespie is a hookup pro, never letting anyone get too close. When he meets Sean, though, he feels a connection right away. An ill-advised threesome seems to kill a friendship in the making, but when they're thrown together by work, it doesn't take long for passion to reignite. Sean calls to something in Jace he never knew was there, and together, they explore a dynamic that fulfills them both. But as feelings deepen, doubts surface. Sean is in the closet, and Jace struggles to trust his promise that it won't last forever. With family conflict and his career in the balance, Sean finds it difficult to picture his life without secrecy, but if he doesn't find a way, he may lose the one person he most wants to please.
