Eliot Lind returns to the night piranhas were released into Cliffside Reservoir. In his past life, rich heir Chase Chandler and others conducted mercy release of piranhas in the reservoir. After Eliot discovered this, he hesitated and failed to close the sluice gate, and the piranhas entered the downstream urban water system through the spillway, causing irreversible consequences. Afterwards, Chase and others falsely claimed "the technician did not close the gate", and Eliot was fired as a result. Waking up again, he is reborn back to the day of the mercy release. This time, he sticks to his principles, and finally achieves a different outcome.
