Charlie (Terrence J) is a bachelor who's convinced that relationships are dead despite his therapist sister's (Paula Patton) and his friends' attempts to tell him otherwise. On a bet he decides to stay with one woman for one month to prove that he is immune to love. Soon, he meets the beautiful and mysterious Eva (Cassie Ventura) and coaxes her into a casual affair. But as Charlie spends more time with Eva, he begins to question whether he may actually want more than just a one-night-stand.
