Cat People (1982): Background Story Part 2

The clip background story Part 2 from Cat People (1982)

Long ago, our ancestors sacrificed their children to the leopards.
The souls of the children grew inside the leopards until the leopards became human.
We were gods then.
We are an incestuous race.
We can only make love with our own, otherwise we transform.
And before we can become human again, we must kill.
Welcome home.
Irena.
Mother.
You must return.
