Shifts in Time

Please read the following:
"In the movie, a young woman receives audio tapes in the mail. The tapes are intended for the previous tenant. The young woman listens to the tapes; they are recordings of 'the sounds of Formosa'.

A young audio technician sent the tapes. He sent the tapes to his ex-girfriend's former address. He didn't know that the ex-girlfriend moved. The young woman got the tapes instead.

The young woman lives a lonely life. She is having an affair with her boss, who is married. One day, she leaves her job and gets on her scooter. She travels through Taiwan to try to find the 'sounds of Formosa' that she hears on the tapes."

--What changes in this passage? In the first and third paragraph, I describe the plot in the present tense. In the second paragraph, I describe the plot in the past tense. This passage is badly written because of the time shift; the second paragraph should be in the present tense.
