There is this guy who is happily married - has a wife and a baby. One day he has an accident and loses his memory. He does not return home all night. The wife worries. She goes to visit him and finds he does not know who she is. She applies to be his secretary so she can work with him. He still does not know her. At the film's end he regains his memory and rushes back.
