Watch Rush Hour Online at Couchtuner. When maverick, wise-cracking LAPD Detective Carter and honorable, reserved, master martial artist Detective Lee—who comes to L.A. to avenge his sister’s alleged death—are paired up by Carter’s boss, Captain Cole, cultures clash and tempers flare. Attempting to help the two get along is Sergeant “Didi” Diaz, Carter’s friend and former partner who doesn’t hesitate to call him out on his antics. Secretly aiding them as an informant is Carter’s cousin, Gerald, a low-level offender who runs with a tough crowd . Yet despite their differences, both Carter and Lee can’t deny they make a formidable team, and grudgingly admit that sometimes an unlikely pairing makes for a great partnership.
