Zhao Xiaofan (played by Zhao Yihuan) has been attracted by the clean uniforms and warm smiles of flight attendants since she was a child, and she is determined to become one of them when she grows up. However, she was born in an extremely ordinary family, and her appearance and personality are ordinary. She is a thorough "female loser". However, the cruel reality did not hit Zhao Xiaofan's confidence in realizing her ideals. After several twists and turns, she finally joined the flight attendant training camp and took the first step towards her dream. In the training camp, Zhao Xiaofan is not only waiting for rigorous courses and huge pressure, but also the open and secret struggles among peers. Coupled with Dean Ling who dislikes her anyway, Zhao Xiaofan is attacked from all sides and is in a very embarrassing situation. However, with her unremitting efforts, Zhao Xiaofan won the recognition of the instructors and the respect of her opponents with her outstanding results, but at this time, she found that she was suffering from vertigo and would be completely out of the job of flight attendant.
