What happened on the road will change them forever...

Thirty years ago, Alex, Bonnie and Kevin went on a road trip to the Grand Canyon with their parents. But something cut their journey short, and they never made it there. Something that shifted the dynamic of their family forever.

Today, Alex, Bonnie and Kevin might be siblings, but they've grown apart, each holding heavy secrets close to their chests. When their mother's health takes a turn for the worse, she asks them to relive that old road trip to see her, and they're forced into close quarters once more.

As the siblings retrace old steps on an epic journey along Route 66, they are led to finally share the parts of their lives they've tried to keep hidden. Along the way, they can learn the truth of what really happened in their fractured past - a past they now have the chance to mend.
