Gayla is trapped when floodwater pours into her bedroom in a residential centre for kids with disabilities. The other children have been evacuated while Gayla waited for her father, but now the streets around are cut off and she's all alone with no way out. Junjun's makeshift shack has been washed away in the flood and he needs to find medicine for his sister, who's sick after drinking contaminated water. At first these two young people seem to have little in common and pity each other, but as the waters continue to rise, can they find a way to work together to survive?
