In the 1980s, women were not supposed to be funny. But when a group of college improv comedians gets the chance to join a new late-night show, it’s Lillian Martin who stands out. The new show was called "The Midnight Show" and it would air every Friday night, live from New York, and change the landscape of TV and comedy forever. But first it would change Lillian’s and her friends’ lives. When the show becomes a runaway hit, the cast is thrown into the spotlight. Lillian, in particular, seems destined for bigger things --- until one winter night in Lower Manhattan, she vanishes, leaving nothing behind but questions. Forty years later, Lillian’s disappearance has still never been solved. But when a budding journalist begins asking questions, she stirs up decades-old drama --- as well as tightly held secrets some comedy legends would much rather stay buried.
