TiMER (2009)

When implanted in a person's wrist, a TiMER counts down to the day the wearer finds true love. But Oona O'Leary faces the rare dilemma of a blank TiMER. Her soul mate - whoever and wherever he is - has yet to have a TiMER implanted. Staring down the barrel of thirty and tired of waiting for her would-be life partner to get off the dime, Oona breaks her own rules and falls for Mikey, a charming and inappropriately young supermarket clerk with a countdown of four months.
