Martingale

In probability theory and gambling, a "martingale" is a situation in which the player doubles down after losses, believing that they'll get to even on their next win. In a sense, that's what the lead character is attempting by searching for her daughter's killer. If you're looking for light-hearted fare, this film is not for you.

While it's bleak and some of the supporting-character dialogue is a bit stilted, overall the movie punches above its weight. Kelly Sullivan as Andi really pulls you in as her convoluted quest unfolds. "Martingale" is an example of what can be accomplished, with a relatively modest production, by focusing on story line and pacing.

Finally, one of the other reviews critiqued the lighting. This movie was shot in western Washington State, and having grown up there, I can confirm that the pervasive cloud cover is exactly what the region looks like. Frankly, the lighting fits the mood of the story.
