Brother and sister Sam and Gray live together in New York and are frequently mistaken for a couple. They decide it is time to branch out and develop new friendships, but complications arise when Gray finds herself falling for Sam's new girlfriend, prompting her to question her sexuality. Romantic comedy, starring Heather Graham, Thomas Cavanagh, Bridget Moynahan and Sissy Spacek.

Sam and Gray are such a well-matched pair that it is difficult to believe they are brother and sister rather than husband and wife. They both share a love of 1940s movies and dancing, and when they meet Charlie, they have something else in common: They both fall in love with her. Sam must deal with unexpected feelings of jealousy, while Gray struggles to come to terms with her sexual orientation.
