Guillermo del Toro once again tries to horrify as after a spooky Don't Be Afraid of the Dark - now, with his next horrendous creature Mama (2013). The story of Mama starts from scene where two sisters Victoria (Megan Charpentier) and Lilly (Isabelle Nélisse) mysteriously disappear in the nearby forest, after their mother was ferociously killed by their father. Lilly's and Victoria's uncle, Lucas (Nikolaj Coster-Waldau) tries his best to investigate this strange disappearing and to find little girls, if it's possible. But days has pass, and his rescue expedition hasn't show any results. In desperation he seeks and seeks his nieces again making it almost the main mission of his life. Finally, when he is about to give it up, he encounters a weird cabin in the forest, where two girls are living on their own, safe and in the good health. And there would be nothing extraordinary, if we talked about days of searching. But, almost five years have passed since, Victoria and Lilly were missed… That asks lots of questions. How little girls survived in the forest alone? Were they alone? And who was welcomed in Uncle Lucas's house alongside with the children? It seems like little girls' mother haunted their minds and what was taken as aftermath of the stress now turns to be a paranormal entity, Mama that has infested Lucas' house. The situation becomes really horrifying when Lucas's girlfriend, Annabel (Jessica Chastain) decides to use hidden demonic powers of Mama to resurrect her own children, which died many years ago.
