The Sugarland Express (1974) on Netflix

In Texas, Lou Jean Poplin has just completed an eight month sentence for petty crimes committed. Her husband, Clovis Poplin, is in minimum security pre-release remand, where he is serving the remaining four months of a one year sentence also for petty crimes committed. Albeit by threatening means, Lou Jean convinces Clovis to break out of remand. The reason?: child welfare services have awarded permanent custody of their infant son Langston to his foster parents who live in Sugarland, Texas. Lou Jean vows to get Langston back by whatever means, and she needs Clovis' help. Early on in Clovis' escape, they take highway patrolman Matthew Slide hostage in his patrol car, he who is to drive them to Sugarland. Captain Harlin Tanner, who is leading the pursuit of the Poplins, sees that the Poplins are basically decent but misguided kids who in their current mission have committed some serious crimes, all which he takes into account when deciding on the appropriate course of action to end the pursuit while trying to protect Slide. But the case takes on a life of its own when the story hits the airwaves, with every Texan having his or her own very strong opinion on the Poplins, what they are doing and how best to help or hinder their mission.
