Nightmare in the Daylight is a 1992 American made-for-television thriller film directed by Lou Antonio, starring Jaclyn Smith and Christopher Reeve.
Sean Farrell (Reeve) is a lawyer working in San Francisco, who in the past beat his long-lost wife, Jean, who disappeared in the 1985 Mexico City earthquake.
One day, he notices Megan Lambert (Smith), a Wisconsin teacher visiting the city with her husband Peter (Mason) and son Jamie (Bell).
After kidnapping her for a short period of time, he contacts his first wife's father, who tells Sean that Megan is not his daughter.
