De 33-jarige Andi en de 36-jarige Benno zijn twee zeer verschillende mannen. Maar ze hebben één ding gemeen: ze zijn beiden zeer ziek en hun dood is nabij. Onder het motto 'carpe diem' willen beiden nog een laatste avontuur beleven. Maar ongeacht hoeveel duizenden kilometer ze reizen en ongeacht of ze naar het einde van de wereld trekken, Andi en Benno vinden geen enkele voldoening in hun trektocht. Misschien moeten zij op het einde wel op zoek gaan naar iets helemaal anders.
Nee, helaas is Der geilste Tag nog niet beschikbaar op Netflix in Nederland.
