In the heart of Amsterdam's Jordaan district, hardworking widow Bet Mager runs a laundry business with her mischievous son Piet and the good-natured Cobus. When she hits the lottery jackpot of 100,000 guilders, Bet leaves the business with Cobus to sell and jets off to Algeria with Piet. From the Kasbah to the desert, Bet plunges into wild adventures—even daring to ride a camel despite her less-than-'skinny' figure. After an exhausting but thrilling journey, she returns to the Netherlands, where a sold business and an unexpected romance await.
