Being a scientist is a very beautiful profession, but also it is a very useful profession. Based on their discoveries, many things are found, things that move the world forward and things that make crucial changes in all fields. The young scientists, Betty and Donald, come into the house of their professor Steven. Steven has been missing for a few days, and there are numerous questions related to his disappearance. He wasn't a person that could disappear just like that, so Betty and Donald are afraid that he might be kidnapped. Namely, his latest discoveries might be the reason for his kidnapping; maybe he revealed something more than he should, so some people decided to kidnap him.
