John Lawlor is a pit bull, DEA agent, married to his job - there's no bad guy he can't stop, nothing he won't sacrifice to close a case. Joey Kang is Taipei's best "carrier" - fast moving and thinking, hard to catch, impossible. These two weren't supposed to fall in love, but fate brought them together... until the forces of crime and corruption tore them apart. Now, 15 years later, fate sends Joey and John in opposite directions during a weekend in Taipei. And these two will realize that the only thing harder than falling in love... is falling in love again.
