Misterio en El Sótano [Mystery in the Basement]

The hiking trail you were enjoying on this beautiful and hot summer day... ... it has become an apocalyptic storm of rain and thunder. Disoriented, confused and soaked, you can see a house in the distance... A local appears and offers to accompany you... it seems your only option. After knocking on the door and getting no answer, he accompanies you to an open entrance. Descending stairs reveal access to a basement. The local lets you pass and locks you up leaving you confined in the gloom... Soon you will begin to understand what is happening there...
