Parents Phil and Claire yearn for an honest, open relationship with their three kids. But a daughter who is trying to grow up too fast, another who is too smart for her own good, and a rambunctious young son make it challenging. Claire's dad, Jay, and his Latina wife, Gloria, are raising two sons together, but people sometimes believe Jay to be Gloria's father. Jay's gay son, Mitchell, and his partner, Cameron, have adopted a little Asian girl, completing one big -- straight, gay, multicultural, traditional -- happy family.
