Friendship makes life worth living, and worth ending too.When Eufrasia Vela begins working as a caregiver for the elderly, little does she suspect that her job will lead her to an existential crossroads. The warm relationships she develops with Do a Carmen, Dr Harrison and "The Magnificent Seven" - endearing characters who capture her thoughts and affections - force her to rethink her role as a mother and sister, the vicissitudes of longevity, the forms that compassion takes - and the surprising value that guinea pigs acquire in her moral compass. Accompanied by a soundtrack featuring huayno, jazz, ballads and pop, the story of One Hundred Guinea Pigs also turns to cinema as a counterpoint to the existence of its characters, and a source of revelations about the meaning of both life and approaching death.
