Step into the shoes of Ethel, a quirky heart-transplant surgeon with an uncanny ability to communicate with the hearts of her patients. After a botched operation leads to an unexpected mix-up, Ethel finds herself in a race against time to uncover whose heart has mysteriously ended up in her patient’s body. As she navigates bizarre encounters with a misfit group of organ donors, stubborn hospital admins, and eccentric colleagues, Ethel must solve puzzles, detect clues in the hospital's secretive underbelly, and build utterly hilarious relationships, all while trying to get her hands ‘heart-deep’ in a case that could cost her career or save it forever. What's more, she must come to terms with her own heart's desires amid the chaos of doctor-patient ethics, mistaken identities, and love–even if it comes in the shape of an unexpected heart.
