Just 18 Summers tells the stories of four families who are at various stages of their lives, and discover the meaning of family and just how fast children grow up.

After the tragic death of Butch Browning’s wife, Jenny, four families begin to realize how precious—and fleeting—their time together is. Each is at a different stage in life: Butch is facing single parenthood. The O’Reillys are expecting their first child.

The Andersons are approaching an empty nest, and the Buckleys are so focused on providing their children with everything that they’ve forgotten what they truly need. With just eighteen summers before their children are grown, how do they make the most of that time when life so often gets in the way?

As summer flies by, each of these parents must learn about guilt and grace . . . and when to hold on to their kids and when to let go.
