When motorcycle-riding Stella Crown hires a new farmhand to help run her Pennsylvania dairy business, she gets more than she bargained for. A Mennonite widow arrives, burdened not only with grief but also by rumors of infidelity and murder. Stella herself is feeling deep sorrow over the loss of her longtime friend and employee Howie and is worrying over her shaky finances. Soon she is also coping with an influx of nasty in-laws, heartbroken beaus, and spiteful vandalism. Determined to protect herself and her farm, Stella sets out to discover the truth while trying to give her new employee the benefit of the doubt.

Meanwhile, Stella's good friend and fellow biker Lenny is riding a crisis. One moment jovial, the next angry and suspicious, Lenny is haunted by pain and secrets he won't share with Stella. His odd behavior is soon complimented by bizarre attacks on his home and business. Now there are two people close to Stella with undisclosed pasts, and the old saying "Three can keep a secret, if two are dead" suddenly gains new and terrible meaning.
