Alena Valkova & Lenka Vyskocilova - Unplanned stop

Alena and Lenka are visiting their friends today but their choice of "shortest route" doesn't seem to be the best option as they are currently at least 30 km away from the main roads and are now lost somewhere in the forest. What's even worse, the car went on strike and the mobile phones show just a simple "network not available" message. After a short discussion Lenka decides to search for help while Alena stays to guard the car. After some time Alena starts feeling pressure in her bladder.
