Two twentysomething Danish sisters try to mend their once-inseparable relationship amid a whirlwind of disconcerting male behavior in “Rule Number One.” A peppy showcase for good thesping and terrific Danish design, refreshing all-purpose relationship comedy entertains with a novel range of strange encounters. DV-originated pic is pleasant fest fare.
A recovered kidney-dialysis patient and former med student, Caroline (Susanne Juhasz) sacrificed her studies to comply with the suburban fantasy of her selfish b.f., Michael (Anders Valentinus Dam). She hasn’t seen her sister, Sarah (Mira Wanting), since the latter chickened out of donating a kidney minutes before surgery four years ago. Their awkward reunion coincides with Caroline catching Michael cheating on her, precipitating an instant split. Extrovert Sarah invites mild-mannered Caroline to move in and sets about fixing her up with a series of guys, but, as one date from hell leads to the next date from Hades, Caroline entertains the thought that a guy she met at a bus stop (Thomas Levin) may be Mr. Right. Title stems from Caroline’s pronouncements about how to conduct one’s life.
