First Lady Nancy Reagan heads for Hollywood to guest-star with Gary Coleman in the kids' sitcom series. The mood, however, is mostly serious: Nancy visits Arnold (Coleman) at home and lectures his classmates at school after reading an article he wrote on school drug abuse. The TV cameo performance marks Nancy's first Hollywood role since she appeared in 1958's Crash Landing.
