"Lagot Ka Sa Kuya Ko" follows two siblings who lived vastly different lives. Alex (Ronnie Ricketts) works as a taxi driver and secretly participates in underground fights. His sister Sarah (Nadine Samonte), recently returned from the US with their mother (Marita Zobel), is a teenager adjusting to life back in the Philippines. Alex unexpectedly encounters Sarah and her mother through Boogie (Dinky Doo), a young rapper he helped after a fight, unaware that they are the family he has been searching for.
