Dee Latener and his half-Japanese partner Randy ("call me Ryo") McLane are a couple of detectives in New York's 27th Precinct. But Dee can't stop chasing Ryo, attracted to his dark hair and dark eyes - or is it something more?

Tired of the daily city grind, these crime-fighting crusaders set off for a vacation in England, to relax, enjoy themselves, and to see if Dee can have his way with Ryo. But when Japanese-Americans start turning up dead outside Dee and Ryo's hotel, the ever vigilant mismatched investigators become embroiled in the local crime scene.
