Un equipo de asesinos apunta hacia una futura boda de dos policías y sus amigos, incluyendo al padrino y a la dama de honor, Alex Cahill.

Mientras se lleva a cabo la boda de Walker y Alex, se contrata a un asesino para matarlos.

Justo cuando Walker y Alex están a punto de irse de luna de miel, el asesino que fue contratado para matar a Alex y cuyo compañero Walker mató, se dispone a atraparlos. Y está decidido a hacerlo. Incluso si tiene que derribar el avión en el que están.

The end is near ... in a show told mostly in flashbacks, a wounded Walker ascends through a manufacturing plant, wounded and using his gun one bullet at a time on killers as he recounts the story of a visiting African businessman who collapses from an Ebola-like virus after infecting several people. The businessman, who has since died of the virus, was a pawn in an African diamond-smuggling ring. Now Walker has the diamonds and a whole cartel is in the building going after him. A "Dallas"-like twist ending keeps Walker going (this show and the one after it were doubled up on the same Saturday night after being postponed due to extremely low ratings).
