The Shining Sky

Please correct the following sentences. Thank you.

When we were wrenching our hands in utter helplessness, saw an American lady came to our rescue.. She told me that she knew what we were searching for; insisted us to watch the fireworks, and started searching for our keys. Now, lit by the fireworks, the sky looked more ominous and showed a pot-pourri of colors. Presently, sparks of light traveled across the sky and transformed into shapes of lions, tigers, elephants and deer. We then, saw a fully blossomed flower with bees swarming it. There were shadows of men and women holding hands, and an American flag was found fluttering. The crowd screamed with joy and excitement. We stood mesmerized, unable to take our eyes from the shining sky.
