A most improbable love triangle, one that appears to have only two sides. Roberto, a full-time barman and part-time musician, meets a lot of women in his line of work. When a tipsy, affection-hungry young woman called Cat slips him her phone number at closing time, he thinks little of it. Even so, there's no resisting the lure of a late night booty call. A week later, another young woman, Cleo, enters the bar. She's smart, very cynical, utterly indifferent to Roberto—and a dead ringer for Cat: same face, figure, hair and eye-colour, even an identical kiss. Are they twins? Both deny it. Is it a case of one woman with multiple personalities? A fiendish fidelity test or a cruel prank, perhaps?
