They grow up so fast.
Brennan Huff and Dale Doback might be grown men. But that doesn't stop them from living at home and turning into jealous, competitive stepbrothers when their single parents marry. Brennan's constant competition with Dale strains his mom's marriage to Dale's dad, leaving everyone to wonder whether they'll ever see eye to eye.
