<<I think a sitcom is hideing in this situation.>>
For sure a romantic comedy.
Maybe even an action thriller as the young lawyer gets closer and closer to Sarah's darkest secrets (she's a guy!) and is almost killed in a moose-hunting "accident" involving Dick Cheney and then again when an upstream dam opens while the guy is fly-fishing in hip-waders. Anyone recall the fishing scene with Warren Beatty in The Parallax View?
