Soo this movie I watched as a kid… Well, a mum (probs in 20’s?) divorced with her husband? But they had a girl together which probs was like 7ish? But then the twi moved to a hotel or a motel? And at night, the mum would discover that her daughter was talking to someone in the walls? Or the vent? But the roof leaked asw… And then I remember the daughter going missing, and the mum suspected it was someone in the hotel/motel… But then she and polices found her daughter dead on the last floor to the rooftop? Thats all I remember =)
