Mia Mills is an aspiring singer with a painful past. Jarren Reyes is a known song writer with a broken heart. When two lonely souls met, they start to create a broken melody.

Sarah Catli is a different kind of woman. She’s a kind of woman who doesn’t need emotional sentimental crap to be happy. Naka-fucos lang siya sa trabaho niya bilang isang FBI Agent. Wala siyang pakialam sa mga kalalakihan dahil hindi naman niya tipo ang mga nanliligaw sa kanya. For her, men are problems and love will give you heartache. Enter the man who rattled her peaceful heart, Shannon San Diego, ang lalaking binuhusan niya ng tubig dahil sa maling akala. He’s annoying, arrogant, full of himself and irritating. He is an INTERPOL Agent who’s going to be her partner in solving a mysterious serial killing. Magagawa kaya niya ng tama ang trabaho niya kung may isang guwapong lalaki na palaging nasa tabi niya at nagpapabilis nang tibok ng puso niya o magiging dahilan ang nararamdaman niya sa binata para manganib ang buhay niya?
