Hawai 5-0: Thanks for the Honeymoon

SINOPSIS

McGarrett is called in to talk to Toni, a tough-talking young woman who has recently been busted along with her boyfriend. Toni is going to prison and can live with that, but she wants to get married (she's pregnant) before then in an elaborate ceremony. In return, she will testify against a mobster who has always beaten the rap -- "How about murder one? ... With his own two hands?" McGarrett counters that the mobster will use all of his many resources to knock off the couple, but Toni is adamant and McGarrett goes to work with the help of the reporter he's dating.
