Married couple Lynn and Doug Kaines (Rebecca De Mornay and Ron Silver), owners of an exotic furniture design company, visit Mexico, while Lynn is in the first term of her pregnancy. On their nighttime return trip, with her at the wheel, they accidentally run into and kill a Mexican police officer in the middle of the road. They make no report of the accident, wary of the perils of a Mexican jail, but slide the dead cop to the side of the road and return to the United States. They have the front end damage to their car repaired clandestinely and appear to have gotten away with the killing.
