Der Schatz im Silbersee/Recap
The "Tramps", a bunch of desperadoes led by the nasty "Colonel" Brinkley (Herbert Lom), kill the owner of half a map leading to a treasure near Silver Lake. The victim's son, Fred Engel (Götz George), sets off in hot pursuit, running into Old Shatterhand. They accompany him to the homestead owned by the resolute Mrs. Butler (Marianne Hoppe), where they are met by Patterson, owner of the second half of the map, and his daughter Ellen (Karin Dor). But the Colonel also wants the other half of the map, and soon the Butler farm is under attack, only to be saved in the nick of time by an Osage war party brought by Winnetou. But the Colonel escapes with many of his men.
The good guys now set out to find the treasure of Silver Lake ahead of the Tramps, going through the land of the Utahs. The Colonel had massacred a Utah village, so the Utahs regard the other group as enemies. But after Old Shatterhand defeats their chief Great Wolf in personal combat, they smoke the peace pipe and offer their help. Unfortunately the Colonel in the meantime succeeded in capturing Fred and Ellen, and now knows where to find the treasure. Leaving his captives behind, he and a few trusted men cross Silver Lake to a cave, where the treasure is guarded by an old blind Indian guardian. The Colonel strikes him down, but then the sight of the pile of gold is too much and the Tramps knock the Colonel out and start to fight among themselves for the treasure. But the Colonel comes to and quickly guns them all down. But in his moment of triumph the dying guardian pulls a chain which sets off a mechanism which hurtles the treasure and all into a mud-filled pit where the Colonel dies.
Back on the other side of the lake, the good guys succeed in freeing Fred and Ellen and overcoming their guards. In the final shot, Winnetou and Old Shatterhand are paddling off in a canoe, onwards to new adventures!
