Award-winning sociologist Arlene Stein takes us into the lives of four strangers who find themselves together in a sun-drenched surgeon's office, having traveled to Florida from across the United States in order to masculinize their chests. Ben, Lucas, Parker, and Nadia wish to feel more comfortable in their bodies; three of them are also taking testosterone so that others recognize them as male. Following them over the course of a year, Stein shows how members of this young transgender generation, along with other gender dissidents, are refashioning their identities and challenging others' conceptions of who they are. During a time of conservative resurgence, they do so despite great personal costs.
