Poor Princess Maria is visiting New York, but she's not having any fun. So her uncle suggests she spend a few days in San Francisco. Unfortunately she's nervous about going by plane. To calm her jitters, she takes a sleeping pill before the plane takes off. Sensing her nervousness, the pilot, navigator and stewardess all secretly give her pills. When bad weather forces the plane to head back to New York, the sleepy princess is left in the care of pilot Edward O'Rourke who takes her to his apartment to spend the night. When she comes to the next day, she finds a note left by O'Rourke asking her to meet him after work. The princess decides to find out what she's been missing and sneaks off to him. To keep her identity a secret, she tells O'Rourke that she's a poor waif sent from Europe to work as a maid in San Francisco. What she doesn't count on is that before the day is through O'Rourke will ask her to marry him.
