Scene One: Waking up wet

Cory is with a chain wrapped from her neck to a weight at the bottom of her pool. She floats, eyes closed, and unmoving. Suddenly her eyes snap open and she realizes her situation. She screams and struggles to free herself.

She tries to pull the weight up, only to find it's too heavy. She tries to remove the chain, only to find it welded closed. She tries to reach to the surface, only to find it too far. Cory is helpless.
