This is a really good remake!! Really loved it! I watched this because I came to know the oroginal was first Indian movie to be remade in Chinese.
Mohanlal's original movie "Drishyam" has many remakes even in India. Most Indians know about the Hindi Version which is tad bit flawed in screenplay and casting.
In Sheep, Lee Weijie (Shawn Xiao Yang) is a movie buff and an immigrant from China, who has fully assimilated in the Thai town of Chanban. He ekes out a living by fixing up Internet connections, raises his daughters with a loving wife in a spacious house (implied to have been a cheap property for being right next to a cemetery), eats and gossips at local joints, prays at Thai Buddhist temples, and follows Muay Thai matches. The rest of his time is spent watching, quoting, and critiquing movies. Save for struggling to bond with an estranged teenage daughter at home and pissing off a corrupt cop on the streets, all is well for Lee.

For his family, not so much. His teenage daughter, Ping Ping (Audrey Hui), is blackmailed for sex by a rich brat, Suchat (Bian Tianyang). While the blissfully-unaware Lee travels out of town, Suchat meets Ping Ping at the tool shed behind her house to have his way with the terrified girl. But awaiting in the shed is Ping Ping’s angry mother, Jade (Tan Zhuo).
