I've Never Been Happier (2009)

Success is a question of confidence, particularly in times of crisis. Life would be unbearable if there weren’t beautiful things to brighten it up a little, including pretty faces. Frank Knöpfel constantly flirts with life with his beguiling bright blue eyes. He buys a complete stranger an expensive coat in a designer boutique just because he feels like it. He disguises himself as a businessman from Oslo, a Mafia boss, a stock exchange specialist and an estate agent, whatever it takes to bring in the cash. He is the type of person who enjoys looking in the mirror, and delights in what he sees there. A flirtation with a customer in a boutique leads to Frank’s undoing.
