Gabe and Noah have been the best of friends for twenty years now. They were more like brothers then just best friends. Their moms had even grown up together, so it was like one big happy family until well it wasn't. push them all too far?
What could break apart these best friends and this unbreakable couple. Love can turn to hate so easily when lies and heartbreak come into play. When it's all said and done can any of them survive this?
Who will betray who? Can they be forgiven? Or will this be the end of the life they once knew?
