A Fatal Lie.

Doctor Willy Prager’s long, selfless office hours come at the expense of his attention-seeking fiancée. During a garden party, Willy is summoned to an ill child’s bedside and leaves his fiancée Erna in the hands of his faithful friend Alfred. Out of sheer boredom, Erna tries to kiss Alfred, but the loyal friend rejects her. Erna feels devastated and lies to Willy that it was Alfred who tried to seduce her. However, Alfred refuses to tarnish Erna’s honour and tacitly accepts when Willy challenges him to a duel. (Stumfilm.dk)
