Pan fydd tad Ali yn dechrau procio Ali am ei dennis, rydyn ni'n dechrau deall bod Ali yn cuddio rhywbeth. Daw pwynt canolog y ffilm pan fydd tad Ali o'r diwedd yn wynebu Ali am gael ei dorri o Team Fireflies. Mae Ali yn gwadu hynny ond yn cael ei orfodi i wynebu’r gwir wrth i’w dad ddangos iddo fod ei gytundeb gyda Team Fireflies wedi’i derfynu. Ynghanol pryder Ali a achosir gan ofn, mae ei dad yn cymryd rheolaeth o dennis Ali fel ei hyfforddwr newydd, ac maent yn cychwyn ar daith dad-a-mab llym, a fydd yn chwalu Ali - yn emosiynol, yn feddyliol ac yn gorfforol.
CUT follows an enormously talented young tennis player, ALI, who gets home from a training session with the best tennis academy in the country — Team Fireflies. When Ali’s dad starts prodding Ali about his tennis, we start to understand that Ali’s hiding something. The pivotal point of the film comes when Ali’s dad finally confronts Ali about being cut from Team Fireflies. Ali denies it but is forced to face the truth as his dad shows him that his contract with Team Fireflies has been terminated. Amid Ali’s fear-induced anxiety, his dad takes control of Ali’s tennis as his new coach, and they embark on a harsh father-and-son journey, that will break Ali down — emotionally, mentally, and physically.
