Bakit 'Di Totohanin

When Katong's (Judy Ann Santos) grandmother accidentally lost their boxing gym in a bet to her father's (Johnny Delgado) rival Martin (Vic Vargas), Katong quickly assumes the responsibility of finding a way to reclaim their gym at all costs -- even if it means competing in a boxing match against Martin's vicious boxer. Knowing that her father will disapprove of her plans, Katong secretly begins her training with her father's former student Paul (Piolo Pascual), a man who happens to be her first love. Will Katong be victorious in getting their gym back when she is distracted by the feelings she has for Paul?
