Based on true life, this fast-paced action thriller depicts one woman's struggle to protect her infant son. In May 1969, Lou Jean Poplin (Goldie Hawn) visits her husband Clovis Michael Poplin (William Atherton) to tell him that their son will soon be placed in the care of foster parents.
Even though he is four months away from release from the Beauford H. Jester Prison Farm in Texas, she convinces him to escape to assist her in retrieving her child. They hitch a ride from the prison with an elderly couple, but when Texas Department of Public Safety Patrolman Maxwell Slide (Michael Sacks) stops the car, they take the car and run.
When the car crashes, the two felons overpower and kidnap Slide, holding him hostage in a slow-moving caravan, eventually including helicopters and news vans. The Poplins and their captive travel through Beaumont, Dayton, Houston, Cleveland, Conroe and finally Wheelock, Texas.
By holding Slide hostage, the pair are able to continually gas up their car, as well as get food via the drive-through. Eventually, Slide and the pair bond and have mutual respect for one another.
The Poplins bring Slide to the home of the foster parents, where they encounter numerous officers, including the DPS Captain who has been pursuing them, Captain Harlin Tanner (Ben Johnson). A pair of Texas Rangers shoot and kill Clovis and the Texas Department of Public Safety arrests Lou Jean.
Patrolman Slide is found unharmed. Lou Jean spends fifteen months of a five-year prison term in a women's correctional facility. Upon getting out, she obtains the right to live with her son, convincing authorities that she is able to do so.
