Niccolo (Mac) Vitelli is the eldest of three brothers and leads their family after their beloved father dies. Their father was a builder and his sons continue in this family trade. At first, they work for Polowski, who does shoddy work and cheats on his jobs. When the brothers can no longer take being employed by such an angry vitriolic boss who takes no pride in his work, they set up their own company. Together, Vitelli Brothers Construction builds houses with pride and care. However, Mac turns out to be an overbearing workaholic, with obsessive concern about the quality of their work and incredible attention to detail. His intensity and driven ambition precludes a happy family life and eventually drives away his two happy-go-lucky brothers from his nascent construction empire.
