Detour (2013 film)

Soon after, his sunroof starts caving in, but he manages to stop it from collapsing using tape and a steering wheel lock.

Roping twine through the pole with a bottle cap, he attempts to force it through the sunroof to measure how deep he is beneath the surface.

The car shakes suddenly, and mud starts filling the pole, causing it to hit his head and make him pass out.

Finally gathering the courage to climb through the mud, he strips down to his underwear and rubs motor oil all over his body to make the escape easier.

With the spare tire on his body for air, he manages to escape through the sunroof and dig through the soil to freedom.
