This cache is placed for the 2021 MWGB
Three Days of the Condor is a 1975 film starring Robert Redford as a CIA operative, but this cache is about the three days it took for the local Flamingos to claim use of the Castle Tintagel from the Nocturnal Unicorns...that's right, the Castle still stands, although the Knights of the roundtable have left the woods.
Note - This is not the final of the 2021 Night Cache, it's just an ammo can in the woods left by a group of very nervous geopups who are scared of Nocturnal Unicorns and Killer Klowns
