The Infernal Walker movie review: Hong Kong undercover police thriller is derivative, but diverting enough

• One is an undercover policeman who’s risen through the triad ranks, the other a triad mole in the Hong Kong police who’s nearing promotion and soon to be wed
• It’s a set-up familiar to anyone who’s seen Infernal Affairs, but Michael Tse and Pakho Chau acquit themselves well enough to make this ephemeral affair fun
