Cooper Lee and her friends in the Hope Street Bible Study Group are enjoying a glorious summer day in the park, complete with a picnic, hiking, swimming, and a local bluegrass band. But Cooper knows that no good day goes unpunished, and when a man turns up dead in the nearby woods-and the sister of Cooper's fiance is named as the prime suspect-the group may have to trade in their prayers of thanks for pleas of divine intervention.

Cooper knows her future sister-in-law is innocent, so when the police arrest her for the murder, the Bible study group must step in to catch the real killer and prevent a grave injustice. Following a twisted trail of clues that leads to a hit-and-run driver, a homeless veteran, and a park full of suspects who may hold more secrets than solutions, Cooper must hold firm to her spiritual convictions before an innocent woman faces a conviction of a more earthly nature.
