Everything can change in an instant ... and take a lifetime to unravel. When Mac McDonald loses his son in an accident, years of bitterness and pain erode his love for his family and leave him angry with God ... and everyone else. Can Mac and his new patrol partner, Sgt. Sam Wright, somehow join forces to help one another when it's impossible to look past their differences -- especially the most obvious one? Every day, we have the opportunity to rebuild relationships and heal wounds by extending and receiving God's grace. Offer "The Grace Card" ... and never underestimate the power of God's love.
