Columbine. April 20, 1999. 15 dead. 23 wounded. The worst school shooting in U.S. history until April 16, 2007. 8 years and more than 40 school shootings later, we still have a lot to learn. Based on interviews with survivors, Adina Taubman's provocative and timely play A Line In The Sand searches for answers. A Line in the Sand is presented as part of the Midtown International Theatre Festival.
