Raam (2005)

When his schoolteacher mother, Saradha (Saranya), is found lying dead in a pool of blood, Raam (Jeeva) is arrested for murder. While Raam is interrogated by police Inspector Umar, the relationship between mother and son is revealed through a series of flashbacks. Mentally underdeveloped and childlike, Raam hardly seems capable of such a heinous crime. Fortunately, two neighbor kids are on hand to help crack the case.
