Tanya is boring. She keeps herself on a strict daily schedule and rarely deviates from it in any way for fear of what might happen if she gets a little bit off course. When she goes to the municipal building to try to get a water and sewer bill straightened out, she has to deviate from her strict schedule.
The slight snag in her schedule is made worse by an elevator that gets stuck between floors and leaves her in a very steamy situation with two other couples that gets completely out of control.
