Jessica Alba will headline the modern-day fable "An Invisible Sign of My Own" says Variety.

"Invisible" revolves around a young woman who has retreated from the world and is consumed by numbers and math. Things begin to change when she becomes a second-grade math teacher.

Marilyn Agrelo ("Mad Hot Ballroom") helms the film, based on Aimee Bender's novel, starting next month. Pam Falk and Mike Ellis (The Wedding Planner) adapted the script.
