Velvet Hotline

Ayingbi Mayengbam, a well-meaning primary school teacher, wants to take on some part-time work over the summer, ideally a job through which she can help people. When her first day as a volunteer at a suicide hotline ends in her finding a dead body, she is done with this line of work. But soon, she is approached by the winsome Dr Rastogi, a man who runs another suicide hotline with a more altruistic approach, and she is unable to say no.
While initially shy and uncertain, Ayingbi learns quickly, her warmth and sincerity enabling her to connect well with callers, her fierce determination to save lives compensating for lack of experience. Over time, however, Ayingbi is confronted with an unfortunate realization: when working at a suicide hotline, you simply can't save everyone. On top of that, there is something sinister afoot at Rastogi's agency, least of which are the three phones in Ayingbi's cubicle, one of which begins to ring without being plugged in . . .
