Candis Cayne has been dominating the small screen on E!'s I Am Cait, but she's getting back to acting next week on an all-new episode of NBC's medical drama Heartbeat.

In the episode, titled "Permanent Glitter," she plays Ava, a trans woman diagnosed with breast cancer. When Dr. Alex Panttiere (Melissa George) recommends an aggressive treatment to save her life, Ava learns that the body she spent a lifetime transitioning into will never be the same.

"The storyline explores the hardships that all cancer patients must face – fear of death and the unknown, and the sometimes crippling uncertainty of what the future holds," NBC says in a press statement.

"And through the character of Ava, we learn that it’s not a breast, or a scar, or our appearance that defines us, but our inner strength and courage."

Catch Candis Cayne on Heartbeat, May 4 at 8/7c on NBC.
