The Bodyguard 2 on AllMovie

A henpecked cop working for the secret service poses as an ambitious singer in order to infiltrate a record company that cushions their bank account by trafficking black market warheads in this prequel to the 2004 action comedy starring Petchtai Wongkamlao. As the undercover cop unexpectedly becomes a singing sensation due to his catchy tunes trashing his ugly wife. Later, as video jock-turned-government spook Paula (Jacquelin Apitananon) begins gathering evidence against the dastardly arms dealers, she and the crooning policeman join forces to crack the case and bust the bad guys.
