Zee's biggest soap launch of 2005 is slated for launch mid March. <em>Sindoor</em>, another women oriented daily soap created by Jay Mehta, is likely to replace <em>Reth</em> and will air at 7:30 pm. Based loosely on the Sridevi starrer Sadma, <em>Sindoor</em> is a story with a difference --- the lead character, played by Gurdip Kohli, is mentally unbalanced, the mother-in-law is overtly protective about her son and no, it is not a saas-bahu saga.
