Noah Braddock remembers Marilyn Crier as the stuck-up mother of his high school girlfriend, Kate. Back then she thought Noah was strictly out of her daughter's league. Now she's appeared out of the blue because Kate's missing, and she thinks Noah might be able to find her -- for old time's sake. But as the investigation deepens, Noah discovers more about Kate than he ever wanted to. A lifetime away from high school, she's been traveling in dark circles, and it's going to take pretty sharp moves if Noah wants to make it back out alive.
