So My Grandma's a Lesbian! (2019) on Netflix

Plot summary

Eva has built her career as a lawyer in Edinburgh, and her engagement to Stuart, heir of the Macdonald family, is announced. That same day her grandmother Sofía telephones: she will marry Celia, her lifelong friend. Eva sees the Macdonalds' conservative morality as a threat to her plans, so she flies to Lanzarote to prevent the wedding. At the airport she misses the bus, and a stranger helps her. At the house she finds Sofía, Celia and her cousin Perla, who lives there, cared for by Sofía. Her mother Natasha arrives to support Sofía. Her brother Said, stranded, has converted to Islam to marry Salima, and he turns up too. Celia asks Bienvenido, the town priest, to officiate the ceremony.
