Dark Roux is the story of a family simmering on the verge of burning to ruin. The delicate nature of this sauce depicts how Cajun culture survives Americanization along parade routes and swamps in South Louisiana. The Mouton family approaches Mardi Gras 1999 expecting traditional joy and release. But teenage struggles with sexual orientation and independence, the ambiguity of young love complicated by the racism of the South, motherhood leaving little room to love one's self (even when two non-family women are waiting to help), and blind ambition as a way to deal with the past, all plague the family. The lines tying them together become taut, threatening to fail and toss them into the hurricane of the future.
