VESSELS follows Diamond, a young Latina transgender woman living in Los Angeles. Diamond works at a garment factory for meager pay and is unable to afford healthcare let alone the breast implants she desperately desires. When her friend Hope shows off her new breasts she obtained through illegal black market silicone injections, Diamond is presented with an opportunity to gain the more feminine physique she has wanted her entire life. The girls go visit the “pumper,” Prayleen, who helps Diamond sculpt the body of her dreams.
