Jessica Fischer moved to New York City in 2000 to pursue a career in entertainment. At the time, she weighed over 300 pounds. While this would be limiting to most aspiring actresses, Jessica quickly found a niche for herself as a stand-up comic and began performing at clubs around the city. At the same time, she began to seriously pursue a gastric bypass in hopes of overcoming her lifelong battle with obesity.

WHAT'S SO FUNNY? follows Jessica’s journey after her surgery. Not only does she lose the weight, but also her drive and ability to perform comedy, which she perceived as her "ticket" into the world of entertainment. While her physical transformation is remarkable, it is the emotional turmoil she experiences afterwards which is truly life changing and proves to be more than she bargained for.
