Mabuhay Ka Sa Baril(1986)

It’s just a matter of survival. He didn’t like it at first, then he gets used to it until he woke up one morning in a maze. There is no way out and he does not have any choice but to use the gun on his hand. Dario/David (Rudy Fernandez), is just a victim, trapped under the name of survival and was hired to kill to lengthen his and his loved one’s life.
