Spain. Kingdom of Leon and Castile, mid-12th century. The noble young man Jacinto was called into his service by a rich and influential hidalgo. Not everyone gets this honor! It’s time to be proud and rejoice - but not when you’re in love with the lord’s wife and therefore hate him in advance. Moreover, it turns out that being a squire is not very easy and everything doesn’t turn out the way you originally thought. Hostility turns into admiration, and former love is forgotten. The choice is not obvious and it is impossible to understand where loyalty ends and betrayal begins.
