'Whistle' is liberally interlaced with the right mixture of romance, comedy, thrill and even supernatural horror.
A seemingly ordinary pizza delivery boy lives with his girlfriend. The couple gets covertly married when the girlfriend becomes pregnant. The girlfriend is a novelist researching to write a horror story, but the hero is totally averse to the very idea of the supernatural.
The movie revolves around the couple's attempts to become financially secure and the convoluted process through which they try to attain wealth.
Combined with many dramatic elements including murder, violence, deception, suspense, mystery, not to mention a haunted mansion, this comedic thriller means to keep the audience on tenterhooks throughout.
