Security consultant and former wrestler 'Jane Smith' receives an envelope with a key to a storage unit that holds a taxidermied hummingbird and clues leading her to a taxidermied salamander. Silvina, the dead woman who left the note, is a reputed ecoterrorist and the daughter of an Argentine industrialist. By taking the hummingbird from the storage unit, Jane sets in motion a series of events that quickly spin beyond her control. Soon, Jane and her family are in danger, with few allies to help her make sense of the true scope of the peril. Is the only way to safety to follow in Silvina’s footsteps? Is it too late to stop? As she desperately seeks answers about why Silvina contacted her, time is running out—for her and possibly for the world.
