This one's for you, Dad.

Caitlin Reilly will pay tribute to her late father, former General Hospital star John Reilly, by appearing in the May 21 episode of the ABC daytime drama — and EW has the exclusive first look.

Reilly will take over the role of Annie, the daughter of Sean Donely, who was played by her father from 1984 to 2013. Here's the logline for the tribute episode: "While mourning the death of W.S.B. (World Security Bureau) agent Sean Donely, fan-favorites Felicia Scorpio (Kristina Wagner), Malcolm "Mac" Scorpio (John J. York), Anna Devane (Finola Hughes) and Laura Collins (Genie Francis) are pulled into a mystery involving Sean's daughter, Annie (Caitlin Reilly)."
