A doting mother is dead and her sickly, wheelchair-bound daughter is missing.

That’s just the beginning of the bizarre tale of Dee Dee Blancharde and her daughter, Gypsy Rose, the subjects of the upcoming HBO true-crime documentary “Mummy Dead and Dearest.”

Premiering Monday, May 15, at 10 p.m., the documentary explores the headline-generating crime involving the mum and daughter. Friends and family admired Dee Dee’s dedication to Gypsy Rose, who seemed to suffer from countless ailments for as long as anyone can remember. And Gypsy Rose appeared to be similarly enamoured with her mother. But as we all know too well, appearances can be deceiving.

A strange Facebook message leads to the grisly discovery that Dee Dee has been brutally murdered and Gypsy Rose is missing. Fearing Gypsy Rose has been kidnapped by Dee Dee’s killer, friends worry how long she can live without the medications and intense care of her mother.

Who could’ve known that the story would turn out to be even more bizarre than a simple murder and kidnapping? Let’s just say Gypsy Rose was able to walk, and that’s just the beginning of what will unravel in the strange case.

Erin Lee Car, the filmmaker who helmed HBO’s “Thought Crimes: The Case of the Cannibal Cop,” directed this true-crime movie also.
