She’s only just arrived, but Annie Murphy is about to g et kicked out of the Plaza Hotel.

The situation would be a fitting one for the character she plays on “Schitt’s Creek”: Alexis Rose, a fallen socialite whose family loses everything in a Bernie Madoff-esque Ponzi scheme. For Alexis, being ushered out of a New York City landmark would be yet another entry in a long line of humiliating losses, including getting dumped by her Greek shipping magnate boyfriend, saying goodbye to her wild life on the international party scene and moving from an affluent neighborhood in an unspecified city to the small town of Schitt’s Creek .

And, O.K., the cause for the hotel banishing Ms. Murphy — a rogue photo shoot staged in the lobby — is admittedly very Alexis too. It probably doesn’t help that, out of character, Ms. Murphy could still pass for a rich hellion of Instagram, with her waterfall of caramel colored hair and precision-winged eyeliner. One of the Plaza’s chief occupations these days is likely trying prevent glossy-maned women just like her from creating influencer content inside its storied walls.

“It would be hilarious if we got kicked out,” Ms. Murphy remarked. She remained un-Alexis-ly pleasant and patient through the negotiations with management until they were finally assuaged. (The Plaza eventually consented to a photo shoot as long as it was limited to one dead-end hallway and there was no flash photography. Otherwise, she was welcome to use the exterior of the building, where any old pleb with a selfie stick can pose.)

Then it was on to the Champagne Bar, which is less intimidating and exclusive than it sounds, but just as expensive. Ms. Murphy’s eyes widened as she read the menu, which includes a champagne and caviar special that costs $895. She instead settled on a glass of more reasonable rosé.
