Adam is forced to bring the kids along to work while he has an important work meeting planned with his boss. It is not until later he discovers that the kids have lice which causes a series of other issues. Meanwhile Andi is upset at the idea that she's a bad mother since she is the only one that doesn't get lice.
When Adam thinks Kate's boyfriend, Tyler, is a pothead, he decides to confront Tyler but doesn't get the support he expects from Andi. As a result, he turns to his dad who was very opposed to weed when raising Adam for some advice, only to find out that his views on the matter have become more liberal.
