Detective John Stark approaches the PI team of Griff Cole and Britt Callahan with a postcard he's sure is from his estranged daughter, Kira. She's been listed as a runaway for three years by Portland, Maine police but John isn't convinced that her continued absence is by choice. As Stark's long-time friends, Cole and Callahan agree to look into the postcard marked only with the letters OK. The postmark leads them to Oracles of the Kingdom, a farm where women sell fresh produce in return for a fresh start with God. But nothing seems right about the town or the farm and Britt goes undercover to look for Kira. Once inside, she realizes that Oracles of the Kingdom is not the refuge it appears.
