“I’m a crazy, drunk flight attendant, not a killer,” says Kaley Cuoco in a new trailer for “The Flight Attendant.” HBO Max’s comedic thriller sees the “Big Bang Theory” alumna playing Cassie, a woman who becomes a suspect in a murder case after the passenger she hooks up with ends up dead. “When I woke up in the morning, he was so alive,” a wholly unconvincing Cassie tells the police.

Worried that she’s “losing [her] mind,” Cassie struggles to make sense of what exactly happened during her fatal one-night stand. “The whole night is just flickers,” she explains. “I can’t remember anything about it.”

“The Flight Attendant” premieres November 26. Rosie Perez (“Birds of Prey”) and Zosia Mamet (“Girls”) costar. Cuoco and Susanna Fogel (“The Spy Who Dumped Me”) are among the series’ exec producers, and the latter directed two episodes.
