THRILLER
The set up has a wife, Lucy Church (Muriel Pavlow) arguing with her husband, Jay Church (Michael Craig) over an expensive purchase. Before she leaves, she then tells him she does not want it there when she comes back, and decides to go to the movies by herself. And after she uses the phone, it was during then she catches Wade (Donald Sinden) attacking the manager, and while his partner, Barney is chasing her through the corridor. The manager then wakes up from his attack before Wade decides to use a gun on him. By the time Lucy makes it to the street, she is then struck by an oncoming bus knocking her unconscious. For the next hour or so has Wade attempting to sneak onto the premises of the hospital, and making several attempts to end Lucy's life with obstacles thwarting those attempts with coincidences.
It is a little outdated, as it looks as if this was during the post war era when all the patients are placed on the bottom floor along with other patients, with anyone able to look through windows of hospitals. For hospitals these days have a right to their privacy and do not have windows where others are able to see them.
