On her wedding day, Sierra Shaw is completely ignored by her groom Henry Lynn, who can't take his eyes off his just-returned childhood friend Chloe Turner. He sticks Sierra in the last car, kicks her parents off the head table, and gets exposed in his group chat for years of lying and shady behavior. Sierra finally sees his cold-hearted betrayal for what it is and calls the whole thing off on the spot, then walks straight into the wedding that Ethan Cooper, her quiet guardian all along, had ready for her. Henry is left drowning in regret, Chloe loses everyone thanks to her total lack of boundaries, and Sierra and Ethan tie the knot, throwing a magnificent celebration that's all their own, finally finding the love, respect, and happiness she always deserved.
