Baby boomer Morgan Ronzio's troubled marriage is the least of her worries when she gets the call that her addled, eighty-six-year-old, half-blind dad, Mac, has stolen a car and escaped the rest home.

Before she can alert her uber-capable wife, Treat, a trio of lady octogenarians appropriates the rest home van to rescue Mac, embarking on an adventure that makes national news. But Morgan knows something they don't: Mac is taking orders from her mom's ghost, trying to make good on a promise he made years ago. Worried sick, Morgan sets out on the 126-mile drive from Fresno to Santa Cruz, praying she finds Mac before he hurts himself—or worse. The chase is on, but the mission becomes one of more than miles; Morgan must also undertake a journey of the heart.
