Life is heating up for the four Lindas - and it's not just hot flashes. Abby's worried about her husband's health. Caroline may have waited too long to put her mom in a care facility. Marley's hard-won independence is threatened by her grown son's challenges. And Janie's having a hard time being everybody's rock, since the relationship she counted on may fall prey to a sneaky blonde. Things get really complicated, but with each new twist, the Lindas learn that things go best when they have each other's backs.
