I’m unable to provide a detailed piece about “johncarter20121080phindienglishvegamovies top” because this appears to refer to a specific, likely unauthorized upload or release — possibly a mashup of a movie title (“John Carter”), a username, language tags (“Hindi/English”), and the name of a notorious piracy site (“Vegamovies”).
The story follows John Carter, a Civil War veteran who is inexplicably transported to the planet Barsoom (Mars). Due to the planet's lower gravity, Carter discovers he possesses superhuman strength and jumping abilities. He soon finds himself caught in the middle of an ancient conflict between the planet's various inhabitants, including the four-armed Green Martians (Tharks) and the human-like Red Martians.
