Every town has its historical mysteries and Helen has just discovered her town's very own. There's a story here somewhere, and the truth to be revealed, and she takes it upon herself to solve it. The mystery man only appears when the conditions are right. He disappears in the blink of an eye. What is his story? Helen sets out to find out everything she can about him.
But there's her college classes to keep up with and her sister too, who's got troubles of her own. Grandma Chen and her Mah Jong buddies might help, but they're more interested in arguing about who's related to who, and telling old stories.
It's all up to Helen to solve the bicycling man's mystery, maintain her grade average, and support her little sister.
