Everyone has an off day...but Malcolm didn't know how off his day would be when he calls in sick to work. Apart from causing himself physical damage as he tries to get through his day, he must also contend with the Bat Girl, a wild child raised in a cave, who has just escaped from a sanitarium. Throw in a deranged president of the United States, a sinister hypnotist, and a dose of media madness, and Malcolm finds out what sick time really means.
