Overview:

Wanda Tarska, an actress, meets Ketty Brinx, an American woman, and they hit it off. They go on a trip to the mountains together, where tragedy strikes. The young American falls into a ravine. The problem is that a knife and a cut rope are found at the scene of the tragedy, and suspicion falls on her companion. There is one more clue: the name Henry Gieras, which Ketty shouted out as she fell into the ravine.
