The rarely seen world of a polygamist family is documented in "Sister Wives," which follows Kody Brown, his four wives and their combined 17 children trying to live as a "normal" family in a society that shuns their lifestyle. Three of

the wives -- Meri, Janelle and Christine -- have worked for years with Kody to develop a cohesive, loving unit, and their marriages produced 13 kids. Then wife No. 4, Robyn, and her three children were added to the family much later, a development that produced mixed feelings, insecurities and uncertainties. Will it disrupt the balance and change the Browns' lives for the worse?

From their unconventional family structure and living arrangements to financial challenges, each half hour episode exposes the inner workings of a polygamist household, revealing the unexpectedly tight-knit and loving relationships between Kody's wives. The series also captures the intense dynamics surrounding a man juggling three wives while attempting to keep it a secret from the outside world- but the general public is not the only challenge that the Brown family unit is facing.
