When she was six, Anna claimed she wanted to be an astronaut. Forty years later, she is nowhere near the stars. Now a divorced doctor, she’s been living a sad life since a tragic event. But for her birthday, her friends have prepared a surprise: they have entered her in the European Space Agency’s call for astronauts. Anna wants to demur but remembers the promise she made to her youngest son, now deceased: that she’d do anything to make her dreams come true. During the selection process, she meets a small group of applicants. Anna knows that her chances are slim but, surrounded by this kind, lively and bright space-loving bunch, she can’t help but believe in the impossible.
