"What Came First?" follows four complete strangers as their lives become intertwined in the biggest traffic jam in Seattle's history. Caught up in the maze of metal and mortal are a twenty-something slacker with no clue about where his life is going, a conspiracy-addled recluse who thinks this is another piece to the puzzle, the tween daughter of a traveling evangelical preacher hell bent on breaking the rules, and finally a young woman who wakes up in the morning not planning to see the end of the day. Their lives and stories weave into each other to create a safety net for some and an unwanted cage for others.
