Senior Katie Consamus, freshman James Canfield and senior Jennifer Stewart will star in “Kid Simple,” a story about Moll (Consamus), a science-fair genius who invents a machine that detects normally inaudible sounds. When the machine gets into the wrong hands, however, she needs the help of her virginal friend (Canfield) to save the universe from total chaos. The show will run in Xavier Hall tonight at 8 p.m., as well as 8 p.m. on Saturday, April 19; Friday, April 25; Saturday, April 26; and Sunday, April 27, at 2 p.m. Student tickets are $6, general admission tickets are $10 and tickets for seniors and faculty are $9.
