A new trailer has gone online for Shane Carruth's Upstream Color.  The film is Carruth's first since 2004's Primer, and his new movie carries the enigmatic synopsis, "A man and woman are drawn together, entangled in the life cycle of an ageless organism."  After watching the trailer, I still have no idea what the plot is about.  I've seen Primer three times, and trying to understand the time travel mechanics still creates a barrier between me and the film's subtext and emotions.  While Upstream Color will probably be just as complicated (if not more so), this new trailer does a good job at playing to the romance and thrills of the story even though the plot remains unclear.  Hopefully, I'll understand the tagline, "You can change your story's shape, but the color will always bloom upstream," after seeing the movie at Sundance.

Hit the jump to check out the trailer.  The film stars Carruth, Amy Seimetz, Andrew Sensenig, and Thiago MartinsUpstream Color opens April 5th.
