Paul, Katie, Gilly and Sarah, are once again pulled into a mystery, that only they could stumble their way into. What starts as an enjoyable trip to Charleston, South Carolina, to celebrate the marriage of two of their best friends, turns into a life or death adventure for the four them.
Following a wonderful Folly Beach wedding, they begin their search for the brother of the best man. He's gone missing, and what at first, looks like a simple case of a man taking a few days away from home, to avoid an angry, former girlfriend, turns out to be much more serious.
Their investigation into the mystery of the missing best man, will have then traveling between two states, asking the Coast Guard for help, dealing with several local police and sheriff departments, a boat manufacturer in Hamburg, Germany, and if that wasn't enough the FBI.
The four have been friends for several years, and while their main goal in life is to enjoy their retirement, and the friendship that they share with one another, they also know that sometimes God has another plan in mind.
Paul and his wife Katie, Gilly and his girlfriend Sarah, are four Christian friends, that rely on God's guidance to lead them in their investigations. Through prayer and faith, the amateur detectives demonstrate how Christians extend God's love through concern and a spiritually driven willingness to help others.
