Although CEO Vera Everson's lover, Ben can't prevail over her college graduates flood of changes to his rail Mail concept, so he walks out. Vera drops by to make up romantically, but a new idea closes their business rift. After Will dumped Kate, she seeks distraction in lance's cooking class, which arouses Will's jealousy.
Ben and Kate panic, complete with cleaning frenzy, when their boasting to have nothing left to do inspires Maddie telling grandpa Randy Fox he can finally visit again. Desperate to pretend she's making something of herself, drop-out Kate signs up as volunteer, but isn't fit for anything and even messes up counseling single teenage mothers. Ben exchanges sneers with dad, whole he reproaches never having taught him man - or other stuff. They plan a picnic and fishing, but end up staking out someone who 'needs a lesson', which only they sort of learn the hard way.
Ben's father Randy asks his help with the business, for Kate steals the quality-time and dumps on her brother to organize the annual PTA dance at Maddie's school. Ben now wants to out-stage her, but can't stretch the petty budget accordingly, so principal Caruthers steps in.
Ben is not amused when Vera waves his pre-anniversary treats as infantile. Yet his interpretation of an open relationship works out even worse. Kate is determined not to waste her second shot at college like the first time, focusing on boys, so she turns down any 'foppish offer'. Instead, she gets involved with her handsome professor ethics, who proves far from perfectly ethical.
