Three-year-old girl disappears without a trace from her wealthy parents’ summer house. The alarm was on all night long and the windows and doors were locked. Investigators do not find any evidence of an abduction and fear the worst.

The trial is circumstantial in nature, but everything seems to point to the parents’ guilt – after all, when you eliminate what is impossible, whatever remains must be the truth.
