Katherine Heigl accepted a role in Ground Zero, a television thriller scheduled to be telecast that fall which was based on the bestselling James Mills novel The Seventh Power, in the spring of 2001. She co-starred as a brilliant and politically-concerned college student who helps to build a nuclear device to illustrate the need for a change in national priorities; the device ends up in the hands of a terrorist following betrayal by a fellow student.

After the terrorist attacks, Heigl recorded a passionate public service announcement for the American Red Cross in an effort to help raise money for victims
