Nozomi Yumehara, a regular student, finds a magical book called the Dream Collet in the library and meets Coco and Nuts, two creatures from the Palmier Kingdom. They plead with Nozomi to restore their world, which has been destroyed by an organization called the Nightmares. By completing the Dream Collet and finding the 55 Pinkies, they can make any wish come true. Meanwhile, the Nightmares are moving into the real world. When Nozomi agrees to help, she transforms into the magical girl Cure Dream and joins four fellow students to form a team of Pretty Cures.
