David “JR” Garcia Jr. was born into a poor family. His father, David Sr., deserted his mother Marlene before he was born because his wife, Ingrid Garcia is pregnant with David “Dave” Garcia, Jr. When Audrey King and her family goes to Tagaytay for a visit, she falls from a set of high stairs. JR saves her life and introduces himself as David Garcia Jr. after she asks for his name. When she gets to the hospital and is asked by the witnesses and her family who saved her, she says it’s David Garcia Jr. – but Dave is given the credit instead of JR.
As she grows up falling in love with Dave, Dave meets JR and they become the best of friends, but their families do not approve of their friendship. Dave’s family thinks JR wants to use Dave just for the money. The siblings’ mothers would not let the two hang out, although their father allowed the friendship to continue. Dave’s grandmother, Elizabeth, and JR’s mother, Marlene, suspects David Sr is keeping the two boys’ friendship alive.
Audrey’s father, Stanley Sr., sends her to Cebu to continue her studies. JR and Audrey have a chance encounter in the airport. Dave and JR enter the Philippine Military Academy where they graduate at the top of their class. The family rivalry becomes worse as everyone finds out that Dave and JR are half-siblings when David Sr. appears on graduation day. Elizabeth exerts all efforts to cover up the truth to the point that she engineers Marlene’s imprisonment. Things become even worse as David Sr. dies from a gunshot wound during a raid by gun smuggling boss Leo Cardenas on his armory on the suggestion of Ramon Lecumberri, JR and Dave’s estranged older half-brother. It would be followed by more events such as the death of Audrey’s mother Loreta, Ramon killing Leo to save Lola Gets and the involvement of Audrey’s younger brother, Stan Jr., in Ramon’s syndicate. Further DNA testing confirms that Dave and JR are twins.
As things develop, Stanley kills Elizabeth over a financial dispute and frames JR. He is imprisoned and escapes with a former enemy, Ka Doroy, as part of a double agent operation with the military regarding the syndicate. He discovers that the syndicate’s boss, “Hunyango”, is actually Marlon Cardenas, Dave’s godfather and Leo’s father.
After JR is hit in a later incident, Dave agrees to a kidney transplant to save his twin in exchange for a civil wedding to Audrey, but the marriage turns out to be fake because of Mamita’s machinations. Dave and Audrey plan a church wedding, but Dave backs out. Audrey ends up marrying JR in church and later bears him a son named Adrian. However, she dies of heart disease a few days after giving birth.
The brothers eventually face off in a final showdown with Ramon, who agrees to surrender after Marlene’s appeals and completing a plan to bring down his syndicate. However, a mentally-insane Ingrid shoots Ramon in the head (while still believing that he killed her husband David) while being taken into custody. He survives the shooting but doctors said the bullets rendered him blind. Dave later commits Ingrid to a psychiatric hospital. Ramon is sentenced to life imprisonment and makes amends with Marlene, JR, and Dave behind bars. The three, who visit Ramon from time to time, now live together with Robert, Adrian, Ula, Angela and Lily. The story ends with a cliffhanger: a woman and her son appears at the Garcia house one evening. They introduce themselves as Emma Garcia (a third wife of David Garcia Sr.) and David Anthony Garcia III.
