Un idéaliste fait irruption dans la vie de ses trois soeurs.
Ned lived a happy life growing organic vegetables on a farm with his hippie girlfriend and his dog named Willie Nelson, but an unadvised incident with marijuana at a farmer's market lands him in jail. When he gets out of jail, he is off to live with his sisters. While Ned is still happy, his sisters are much less so after he manages to screw up one marriage, one job opportunity, one budding relationship and one domestic partnership. He sees those problems as breakdowns in communication, but his sisters see him as an idiot.
