Big family. Big dreams. Big problems. Big Love. Season one begins exploring the evolving institution of marriage through one atypical family. Bill Henrickson is a practicing polygamist who faces a myriad of challenges in meeting the emotional, romantic and financial needs of his three wives and seven children as they live together in suburban Salt Lake City.

In Season Two, Bill—who owns two hardware superstores—is facing a myriad of personal and professional crises brought on by the exposure of First Wife Barb as a polygamist during a high-profile ceremony in Season One. Bill’s other wives, Nicki and Margene, pick up the slack as Barb languishes in a melancholy funk, leaving Bill to assess the damage the scandal has caused—and to track down the villain responsible for them being outed.

In Season three, Bill Henrickson, who last season bought a gaming-machine business to supplement his Home Plus superstores, is looking to diversify even further in the face of a flat do-it-yourself market and a crackdown on polygamists around the country. It's not a polygamist-friendly world out there and that's why Bill wants to protect his growing family by diversifying his businesses, building goodwill in his neighborhood, and adding a new wife who can deliver him more children.

In Season Four, as a new maelstrom of personal issues swirl around him, Bill launches yet another business venture: a Mormon-friendly casino he planned in Season Three with Native American partners. At the same time, Bill eschews a chance to seize the prophet mantle at Juniper Creek in favor of an even more high-profile calling: running for State Senate in Utah!

As season five begins, the Henrickson family encounters a wave of hostility from neighbors, Home Plus employees, casino partners, students at their kids' schools, even fellow polygamists hoping to keep their personal lives private. Meanwhile, at Juniper Creek, Alby Grant returns from a self-imposed exile with a new mindset...and revenge on his mind. Can the Henricksons stand up to this flood of ill-will?
