Summer Pozzi (Lara Phillips), a Chicago-based flight attendant for an unnamed airline, is mentally preparing to quit her job and marry Jim, her soon-to-be airline pilot boyfriend. During a layover, she gets a phone call asking her to transfer to San Francisco. Then, Jim tells her he refused to take a final exam to be a pilot, unable to have the lives of many passengers on his shoulders. Shaken and disappointed, Summer decides to go ahead with the transfer, and promises herself not to fall for another man too quickly.
