Wilfred Prescott (Alfred Drayton) and his wife Joyce (Beatrice Campbell) find that their large country estate house is haunted. Pictures are found turned to the wall, a bearskin rug catches fire, and a window is broken. What's worse, their daughter, Audrey (Gwyneth Vaughan) seems possessed sometimes by this female spirit.
With the help of friend Vincent Ebury (Robertson Hare), insurance investigator Joe Harris (Gordon Harker), and self styled ghost buster Spenser (Garry Marsh), Prescott tries to get rid of the poltergeist.
What follows is a night of comedic slap stick spiced with some clever special effects as the ghost raises windows, levitates plates and vases, and generally bamboozles the ghost hunters. Spenser tries to get a photo, Harris uses a bottle of bug spray as a weapon, and Prescott tries shooting it with a shotgun. It's all quite lighthearted and amusing. Can they ever get this spirit out of the house?
Although uncredited and never seen on camera, Patricia Owens provides the laughing voice of the poltergeist.
I just watched Things Happen at Night (1948) on YouTube. The complete movie is available there. I don't know think it's ever been released on DVD. It's a pleasant way to spend an hour or so.
