I'm So Excited! takes place almost entirely aboard a plane filled with colorful characters such as a psychic, a hitman, and a virgin looking to lose her virginity. However, when it is discovered that the landing gear is malfunctioning and the plane must circle in the air until the issue can be resolved, the passengers and crew turn to alcohol and drugs to numb their fear and anxiety.
Meanwhile, on the ground, a team of technicians and government officials scramble to find a solution to the problem, while the airline's office tries to keep the news from leaking to the media.
As the flight becomes more and more chaotic, the crew puts on a musical performance (to the tune of the Pointer Sisters' "I'm So Excited") to distract the passengers and lift their spirits. The film's themes of sexuality, religion, and personal identity are woven throughout the story, and as the plane nears its crux, the characters are forced to confront their own demons and find a way to survive.
Overall, I'm So Excited! is a silly, over-the-top comedy that showcases Almodรณvar's signature wit and flair for the absurd. It may not be one of his most significant films, but it's a fun, lighthearted romp that entertains from start to finish.
