Step Brothers movie synopsis: Brennan Huff (Will Ferrell) and Dale Doback (John C. Reilly) are two unemployed and spoiled men who still live with and are reliant on their parents. Brennan, who lives with his divorced mother, Nancy (Mary Steenburgen), and Dale, who lives with his widower father, Robert (Richard Jenkins) must now share a room. Initial antipathy threatens the household's peace and the parents' relationship. Dad lays down the law: both slackers have a week to find a job. Out of the job search and their love of music comes a pact that leads to friendship but more domestic disarray compounded by the boys' sleepwalking. Hovering nearby are Brennan's successful brother and his lonely wife: the brother wants to help sell his step-father's house, the wife wants Dale's attention, and the newlyweds want to retire and sail the seven seas.
