Basically Thanos is obsessed (or in love) with the entity Death. He wants to seek her approval by wiping out 1/2 the population of the entire universe. He acquires the 6 infinity gems, which control all aspects of reality, and places them in his gauntlet to take control of all the universe. His first action is to literally wipe out 1/2 the population of the entire universe in a snap of his fingers.
What heroes (and villains) remain alive have to band together to find and stop Thanos and take the gauntlet away from him and restore the Universe to its original state.
