Celeste is a widow living a tranquil, unadventurous existence in Havana, fulfilling her daily shifts as a tour guide at the local planetarium. One day when several “Cubans” mysteriously vanish into thin air, the government announces that aliens have been living in Cuban society disguised as humans, and that these foreign guests are now returning the favor by inviting humans to visit their far-away world. It all makes perfect sense to Celeste – she had always thought that her “Russian” neighbor Pauline was eccentric, but now learns she was truly from another planet! Celeste discovers that Pauline has left her a personal invitation to join her and joins the government preparation program to journey to the far unknown.

Cuban director Arturo Infante’s film mixes absurd humour and wry political commentary as it follows a kindly planetarium worker who accepts to leave everything and everyone she knows to embark on an adventure that will change her life forever.
