The disappearance of three-year-old British girl Madeleine McCann from a holiday town in Portugal in 2007 was a case that gripped the world – and still does almost 12 years later.

Now, a new eight-part docu-series about the tragic mystery is coming to Netflix. The Disappearance of Madeleine McCann gives a “detailed look” at the case, and posits the theory Madeleine, who would turn 18 this year, is still alive.

“We’re trying to lay out as much detail as we can about the case—and if it could jog someone’s memory in some way then that would be amazing,” executive producer Emma Cooper said in a statement.

“Keeping any search for what happened to Madeleine in the consciousness—particularly globally—is something that’s so important. As we show in the documentary, other children are found—so you have to hope.”

The main theory put forward by the series is that the little girl, who vanished from the holiday apartment where she was staying with her parents, is that she was abducted by human traffickers.

The documentary will be available to stream on Netflix from Saturday March 16.
