Two adults. One kid. No grown-ups.

Walden Schmidt and Alan Harper have spent another year searching for the ideal life. Alan thought he#d found his soulmate in Lyndsey's future sister-in-law, but it wasn't meant to be. An attempt to restart his chiropractic business led Alan to disappointment as well. On the plus side, he met his niece, Jenny, who turned out to be just like her father - a partier and a womanizer. Walden also had his share of ups and downs. Just when an old flame returned and he decided she was 'The One,' someone else turned up and he was sure she was 'The One.' In the end, neither one was 'The One.' Berta remained at their sides all along, keeping them grounded. Meanwhile, Evelyn reached contentment, having gained a granddaughter, Jenny, and a 90-year-old billionaire husband. In this final season, Alan and Walden will continue their search for true love, contentment and the meaning of life. And they may actually find a couple of those things!
