Gracie made her first screen appearance at the end of the First film along with her three other siblings being feed by Delores Bickerman, the Crocs remained in Black Lake after their Father was relocated and their Mother was killed. For over 10 years they lived in the Lake and at sometime they killed Delores and were then taking care by her sister Sadie, where she continued watching over them and began feeding them Beef rejected by the FDA. The Crocs would also feed on local wildlife but their primal nature would take affect and they began preying on the local residents.
Gracie first appeared in Lake Placid 2, as Sheriff Riley, Emma, and Frank were driving around on the Lake with the Sheriff's boat, Frank had fallen out of the boat but recovered. Just as Emma says there are no Crocodiles in the Lake Gracie appears slowly swimming toward the boat, as soon as she reaches the boat she knocks everyone off and begins ripping the boat to pieces. She then begins swimming after the Sheriff and Emma but retreats due to Struthers arriving in his Plane. Gracie would not appear again until the end of the film when Sadie is attempting to throw Kerri to Gracie as she swims up to the dock, Kerri manages to escape and Gracie instead pulls Sadie in and devours her. Scott and Kerri watch in shock until Gracie jumps out of the Lake onto the dock where she begins chasing after Scott and Kerri toward the house. Scott and Kerri manage to get inside the house and hold the door from letting Gracie in. Gracie retreats into the Lake with Martha as they make their way back to the Nest. After Martha is killed Gracie arrives and bites off Struthers head as he is hanging from a tree, Riley attempts to shoot her with a grenade launcher but misses. Gracie runs after Riley but he is pulled out of the way at the last minute by Scott who came to tell him about Bickerman lying about Gracie. Gracie then goes after Emma, because she has the eggs. Riley attempts to set off the Bomb thats in the Nest but it doesnt work instead Scott tosses him the grenade launcher, he shoots Gracie in the mouth and sets off the bomb, blowing Gracie to pieces.
Gracie would appear again in Lake Placid 3 through archive footage of her killing Sadie, as her nephew Nathan rethinks the events in his mind.
