Plot
A murky and polluted lake lies in malevolent hibernation behind a neglected cottage. Suddenly a large plastic garbage bag is thrown into it. It floats amidst the murk, hits the surface, and bumps clumsily into the base of a tree. Silence; until the plastic bag lunges and clings to the tree's branch. 2 girls (Olivia and Christina) stand at the edge of the lake, looking at its nauseating state. 3 others (Summer, Nicole, and Ana) are taking their suitcases out of the SUV parked in front of the cottage. Summer mentions how creepy it is. Ana confirms that it's absolutely perfect. Nicole drags her massive suitcase up the driveway. Christina and Olivia give each other a look, a nod, a smile; "well, let's do it." Isolating themselves for health and cleansing, 5 girls find that you need more than water to survive the past.
