The official synopsis of the episode reads as follows:

Juliette is back in the news and back to feeling like her old self, following her rooftop performance high above Highway 65, but while she enjoys the attention, her team has growing concerns that she may be suffering from postpartum depression. Meanwhile, Will is surprised with an unexpected visit from his father, and learns his private life is about to become public when a tabloid obtains photos of Will and Kevin together. With Deacon's cancer diagnosis no longer a secret, he and Rayna grapple with the future and the real possibility that their time together will be cut short.

Meanwhile, stills and the official synopsis of Nashville's season 3 finale have been released online.

According to the official synopsis, "In the third-season finale, Juliette prioritizes completing her album above all else, leading Avery to make a huge decision. Elsewhere, Rayna and her daughters gather by Deacon's side as he fights for his life."
