As a child, Alberto lost his birthday in the Spanish civil war. Now an old man living a simple life, he rarely thinks about his disappeared past. But when his grandson discovers his Apu has never had a birthday party, never blown out candles on a birthday cake, and never received a single card or present, he's determined to do something about it. As the two set off to find Alberto's birthday, they have no idea it will be a journey that takes them through Spain's troubled past, to places - and people - that Alberto once knew. But in a country that has vowed to move forward, looking back can be difficult. Will they be able to find the memories they're searching for?
