The title “Gunpowder Milkshake” makes sense, because like the cold drink, it’s an enjoyable summer treat.
Karen Gillan stars as Sam in “Milkshake,” a young woman who works as an assassin for a mysterious agency known only as The Firm. The agency is helmed by a man named Nathan (Paul Giamatti), who sends Sam out on her assignments.
While her latest mission seems straightforward, though, it turns out to be anything but. Caught in a conflict between two violent faction related to Sam’s assignment is a young girl named Emily (Chloe Coleman). Sam decides to get involved and protect Emily, but it only complicates things as hitmen are sent after her. In response, she looks to get help from her past.
