Isaac and Luca start an unlikely friendship over a knitted sweater that grows into more, but both men need to straighten out their own lives before they can start anything real. The advent of a catnip-addicted orange kitty pushes Isaac to start building a life that's uniquely his own. With a little bit of growing and some help from Euclid, Luca and Isaac learn that something real is what you make of it, and with a little bit of elbow grease, the possibilities are as sturdy and as beautiful as their wildest dreams.
