Zack Sheldon doesn't have time to be lonely. He's in his last year as a pediatric resident, almost married to the job, and busy with the joys and sorrows that come with providing medical care to children. Professionally, he's confident, accomplished, and respected. But personally he's too insecure to approach a sexy man like Sergio Quartulli, or even to imagine that Sergio might be attracted to him.
Zack spots Sergio from across the gym, and then a chance meeting poolside somehow turns into a date. Before Zack knows it, they've become a couple, but Zack's white coat is his closet at the hospital, and committing to a relationship with Sergio makes it difficult for Zack to continue hiding behind it. On the other hand, he grew up in a small town where being gay was shameful, and he works in an environment that can sometimes be homophobic, so it's hard for him to open up about who he really is. Before Zack can make a choice on his own terms, circumstances force him to make a decision. He can continue to hide, or he can step out from behind his white coat and risk everything for love.
