Black Phone

Chen Lin, a debt-ridden young man, returned to his hometown to inherit his old house and fished out a strange black mobile phone from a dry well. From then on, he was forced to perform various horrific tasks - watching the fish pond at night and being surprised to see dead fish with hair, burning paper in an ownerless grave and being haunted by a ghost baby, sneaking into the crematorium to steal ashes... Every time he completed a task, he gained an underwater power and his body gradually transformed.
