Ever since her 2003 directorial debut "Hebi Ichigo (Wild Berries)," a black comedy about a dysfunctional family, Miwa Nishikawa has been exploring the infinite human capacity for duplicity and the elusiveness of truth.

In 2006's "Yureru (Sway)," two brothers sleep with the same woman and one ends up testifying in court against the other, saying he saw his older sibling push her to her death from a bridge. What really happened, though, is left in doubt. In 2009's "Dear Doctor," a kindly old doctor in a rural village is exposed as a fraud. But his motives remain mysterious.

Like these previous films, her latest, "Yume Uru Futari (Dreams for Sale)," could have easily been made as genre entertainment; in this case, a caper comedy.
