Ep 12. Number One with a Bullet (Part 1)

Ray Santoro, a member of the Kumu, kills Bernie Adams, a member of the mainland syndicate, in order to force his way into partnership with an unwilling Sonny Kanekoa, the owner of a flourishing discotheque. Santoro, impressed by the singing talent of Sonny's sister, Yvonne, tries to take over the management of her from her current manager-songwriter, Johnny Munroe. McGarrett is investigating the murder of Adams as he suspects that what he sees is merely the tip of a very dirty iceberg.
