Croisieres Siderales is a contemporary fable owing more than a little to Sleeping Beauty. Lovely Madeline Sologne agrees to participate in an experimental space launch. When she returns to Earth, she discovers that 25 years have elapsed and she has remained virtually untouched by the passage of time while those left behind have aged dramatically. Sologne's lover Jean Marchat determines to go into space as well so that he and Sologne will be the same age. Makes sense. Croisieres Siderales is an enchanting piece of whimsy, filmed in France just prior to the Nazi takeover.
