Uninvited plot
Lilia Capistrano attends the lavish 55th birthday party of corrupt billionaire Guilly Vega at his mansion. She plans to assassinate Vega for the death of her only daughter Lily ten years earlier. She scouts the party and meets her targets: Vega, his apathetic wife Katrina, his drug-addicted and rebellious daughter Nicole and her boyfriend Mark, his right-hand man Jigger Zulueta, and his henchmen Celso Batac and Randall Ballesteros. Vega also invites his political enemy, Colonel Red. Uninvited to the party, Lilia assumes the identity of Eva Candelaria, who has donated a large sum of money to Katrina's foundation.
