Movie where engagement ring gets left in cab of taxi

An American-born Chinese economics professor accompanies her boyfriend to Singapore for his best friend's wedding, only to get thrust into the lives of Asia's rich and famous.

When she learns she's in danger of losing her visa status and being deported, overbearing book editor Margaret Tate forces her put-upon assistant, Andrew Paxton, to marry her.

An undercover cop lets his job get personal while on an underground assignment.

Having already left three grooms at the altar, Maggie Carpenter is branded "the runaway bride" by jaded New York journalist Ike Graham. But, after his facts are called into question, Ike races to Maggie's hometown to save his reputation and report on her upcoming fourth trip down the aisle – during which he's convinced she'll run again. Though he's there on a muckraking mission, Ike can't help but fall for this breathtaking heartbreaker.
