The main characters of the series are Olivia Benson and Elliot Stabler. They're Special Branch detectives. Their duties include the investigation of particularly serious crimes. Namely, they solve sexually motivated murders.
For example, among their cases was the murder of an underage model, who was first beaten and raped. Or another confusing task – to find out why a young girl fell out of a window. During the investigation, it turns out that her father is a pedophile. But is he to blame for the death of his daughter? The riddle will be solved only at the end of the series.
The cases of this pair of detectives are very difficult. And sometimes a crime needs to be solved in a very short time, for example, in just a few days.
