For Julie and Dave, there's the financial stress of being a one-income family, the sense of being pulled in a hundred directions by the needs of their adult children, and the strain placed on their marriage as the stress and exhaustion of caring for a baby takes hold. Rachel, the eldest Rafter child, struggles to find balance between her high-flying new job and her relationship with Jake; Ben, recently and blissfully married to Melissa, is trying for kids until a heartbreaking accident shatters his world; and Nathan is agonisingly estranged and ultimately divorced from his wife Sammy. Add to the mix, new family members Coby and Dave's father, Tom, and life for the Rafters has never been more packed.

Season four traces the family's fortunes as they attempt to rebuild their lives in the aftermath of Melissa's death. Strong family bonds ensure that traumatised Ben receives warm support as he takes his first steps back into the work-force. Slowly he learns to smile again, embracing a newfound interest in gardening and a growing friendship with his boss's daughter Emma, which might hold the promise of something more. There are further love issues in the Karandonis household, with Carbo and Retta choosing to elope rather than face the comic extravagance of a Karandonis wedding. Julie and Dave, meanwhile, are forced to deal with the consequences for Rachel and Jake of a dangerous accusation flung at him by a drunken woman on a rugby weekend away. Rachel's feelings for Jake are tested to the limit, especially when her boss throws into the confusing mix the chance of a lifetime to work in New York. The Rafters also wrestle with the unexpected arrival of new family members, not the least being the release from prison of Dave's father, Tom. Tom's never quite predictable manipulations ultimately force Dave to take a heart-breaking stand, and cause him to initially misjudge the intentions of his half-brother, Matt. Julie meanwhile finds a new best friend in Donna, though their initial exchanges are hilariously unpromising. Meanwhile Nathan is searching for new direction in his life and his desire to travel forces Julie and Dave to undertake some soul-searching of their own. Ted is also keen to find a greater purpose, mentoring a troubled twelve-year-old boy.
