Two brothers in conflict sire half-twin sons, as they battle to determine the fate of a property dynasty. Intertwined conflict and humor are the lifestyle hallmarks of the relationship between 18-year-old twins Aaron and Josh. Aaron, as the too-young manager of the family's large rural property, sees himself as in his rightful position. Josh (as a worker on the property) sees his own rightful position as not having to take orders from Aaron. One instance of their difficult relationship results in Josh having to take the blame for Aaron's irresponsible driving, when Aaron nearly causes a head-on collision with a Highway Patrol car. Tash (Aaron's girlfriend) becomes pregnant to both Josh and Aaron, that is with half-twin sons due to heteropaternal superfecundation and they all have to live with the consequences.

Due to the untimely death of their Grandfather, Charlie, Aaron and Josh find themselves bidding against each other at a public auction for their shares of the family property. Elizabeth, Mother of Aaron and Josh, has their secret past outed to her sons. A financially over-committed Aaron is forced to sell his part of the property to Chinese investors. As the supreme irony, Josh becomes a resentful Aaron's boss. The 5-year-old sons of Josh and Aaron act beyond their years to protect Tash from Aaron's excesses towards her. Aaron accepts that he has been the cause of much family conflict.
