The fifth installment in FX's anthology series plans on returning this fall, and so far the network has been very scarce on details outside of casting.

During FX's Television Critics Assn. press tour, Murphy, Brad Falchuk and the cast of 'American Horror Story: Hotel' finally broke their silence on the the season's premise, along with their characters.

It was revealed that the story will be based on a real life occurrence that took place in a Los Angeles hotel on a surveillance camera. The footage showed a young woman who was acting strangely and then never seen again.

"It is called 'Hotel,' and it's set in a hotel," Murphy said. "We deal with a lot of American horrors, [including] addiction."

The character descriptions for the season was also revealed:

Lady Gaga: The singer plays Elizabeth, a "wealthy social doyenne," Murphy said, adding that she's "consumed with art and fashion and people, and she has a nefarious plan that is revealed in the first episode."

When asked about LGBT storylines in season five, Murphy revealed that Gaga's character is bisexual. "Lady Gaga plays a character who has relationships with Matt [Bomer] and Angela [Bassett] and Cheyenne [Jackson]."

Sarah Paulson: "I play Sally. I live at the hotel, I hate Iris [Bates] in a rather ancient way for reasons that are revealed quickly. I have a sort of budding relationship with Wes' [Bentley] character."

Kathy Bates: "I play Iris...I run the hotel. I have relationships with Matt Bomer and Wes [Bentley]. And I can't stand [Sarah Paulson's character]. I don't know if I get to work with Angela [Bassett]. I hope."

Angela Bassett: "I'm sexy, have a strong long lasting relationship with Stephanie's [Lady Gaga] character," Bassett said, adding that she plays a fabulous actress who doesn't live at the hotel, but visits often. "I'll probably be at odds with Donovan [Bomer] - who gets the girl?" she teased of the characters fighting over Gaga.
