This is probably a tough one cause I have only a brief recollection. But I remember this movie about a married woman who is a hostage during a bank robbery where the thieves also take hostages clothes for some reason. In her underwear, she accepts a ride from another hostage (a man) and once in his car they begin an affair.
The robbery was only secondary and a brief scene in the movie, and is honestly a dumb plot device to cause the married woman to end up in her underwear in a strangers car.
Any help is appreciated.
