Tú También lo Harías plot
During an armed robbery on a bus, all three robbers are killed. The killer manages to escape and the six witnesses on the bus can't seem to identify the fugitive. Agent Fran Garza and his partner - and ex-associate - Rebeca Quirós, who is in charge of the case, suspect that the witnesses are not telling the truth: the six claim not to have seen the killer's face. However, everything indicates that they have made a pact of silence to protect the fugitive.
