Chris wants to travel to Moscow to propose to Natalie, but Paul convinces the group to first visit Chernobyl with an extreme tourism guide. They meet the guide Uri and another couple who are also going on the tour. Uri explains that because of the radiation levels he can only take them to Pripyat, a deserted city very near Chernobyl. They travel by van, but are stopped by a military checkpoint that makes them turn back. Not giving up, Uri finds an alternative route to the town. The group spends the day taking photographs and exploring abandoned buildings. Uri becomes nervous and decides it's time to head home. However, the van won't start and they discover the engine was sabotaged. Soon they discover that they are stranded, no one knows they are there and that they are definitely not alone.

Georgia is an American academic who's lost her teaching job in Athens. She's taken a job as a tour guide, but she hates it and it shows: the tourists, mostly American, are bored with history and facts; they want to shop. Every group has a goofy couple, a frat boy, a sullen teen, a feuding couple, divorcées looking for a mate, and a funny guy. This group is no exception, plus there's no air conditioning and a bearded silent driver. Thanks to an unlikely friendship, plus daisies, an ice-cream cone, the history of syrup, and the Oracle at Delphi, Georgia may have a shot at finding her kefi during this four-day tour.
