“Doctor Odyssey,” Ryan Murphy’s upcoming ABC drama starring Joshua Jackson, Phillipa Soo, Sean Teale and Don Johnson, has a new cast member: Shania Twain.

The country singer's guest role was revealed in a new trailer that offers the first look at the stressful environment of the medical procedure on a cruise ship.

According to the series' official logline, "Max (Jackson) is the new doctor aboard a luxury cruise ship where the crew works hard and plays even harder. It's all hands on deck as Max and his small but mighty medical team navigate unique medical crises and each other, miles from shore."

In the trailer, Max is welcomed to the Odyssey by Captain Robert Massey (Johnson), who tells him, "This ship is heaven. Our mission is to save the dream. And that's why you're here. Keep these dreamers safe."
