Sienna endures six humiliating years of April Fools' Day pranks from her wealthy fiancé Austin, who repeatedly stages elaborate fake proposals only to mock her tears before his laughing fraternity brothers. Desperately clinging to love, she forgives every cruelty until she overhears Austin bragging at a bar that their entire six-year relationship was merely an ongoing wager among his friends.
Refusing to be his punchline any longer, Sienna flings her mock ring into the dirt and boards a one-way flight to the Irish countryside. When Austin realizes she has truly vanished, panic replaces his smug arrogance as he races across the ocean, arriving just in time to watch her exchange genuine vows with a devoted man who values her heart.
