Day 26

Twenty six days after an undescribed biological disaster, two survivors are forced to live in cumbersome protective biohazard suits and scavenge for food, water and petrol in a desolate, dead land. The two follow the incomprehensible sounds of the radio in search of fellow survivors. They stop for supplies at a farm house when the unthinkable happens.

Edit: The video used to be freely available online, but it looks like now you need to rent it.
