A Lonely Woman (1917)

Sinopsis

Professor Bjørn has spent years and months developing a serum against cancer. When he finally succeeds, he pays for it with his life – the professor’s assistant Jakobsen kills Bjørn to get hold of the valuable formula. The hunt then moves onto the professor’s daughter Rosa, who is the only one left who knows how to develop the serum. When she suffers amnesia in connection with an accident, the recipe seems to have been lost. However, Rosa’s subconscious mind hides more secrets than she realises herself. (Stumfilm.dk)
