Jim, Voskhod 2. Something went wrong with the engines/control systems in the capsule, plus parts that were supposed to blow off before reentry didn't, so they had to land manually. It threw them off course by almost 400 km and a search party had to be put out to find them. Then the area they landed in was so densely wooded that the helicopters couldn't pick them up. Accounts on the wolf encounter vary a bit, but it's either they heard the wolves and it was mating season (making them more aggressive. Same for bears in the area), or the wolves were actually scratching at the partially open capsule door.
